Thank you for confirming what I suspected with regard to accessing the rear Air Fuel(A/F) sensor - otherwise known as B1S1 sensor. B1 = bank 1 - S1 = sensor 1 or A/F sensor - the upstream sensor. No way the get to the electrical connector portion from the bottom unless your forearms are 2" in circumferences at 5' long and you can see what isn't visible from below. If you have never done a spark plug change on a 2GR-FE engine - then do as this man has done. Get the 2 cowling pieces off + wiper arms/motor. It will greatly simplify the job and takes little or no time to do.
Want to comment that O2 sensors (aka A/F sensors) are like spark plugs and they do wear out. These sensors are not cheap hence the reluctance by owners/drivers to replace them when they go bad. But I've seen invoices for over $500 charged by shops to replace them.
Thank you saving me so much time reading. :-) followed every step but didn’t need to remove the plenum. Yes a little awkward to get to but these steps nailed it.

Thanks for sharing. Could be you might only need new spark plugs. Replace the plugs and trade the firewall cylinder head coil packs with the radiator side cylinder head . If you get a misfire code, the defective coil pack would be easier to get to and replace.

I think after a few more times viewing your video I'll jump into the deep end and do this myself this weekend. Thank you so much for the useful information! I do have one question, what is the gap measurement for the spark plugs?
Great video I’m looking to do this job as well I already have all the parts I just wanted to know which o2 sensor is the upstream left and upstream right?
They're both the same except for the length of the sensor wires. Some manufacturers keep them long so they are interchangeable between the left and right.
If you're asking about the O2 sensor I'm replacing in the video, it's screwed into the top portion of the exhaust manifold below the firewall. The hard part is getting to the O2 plug which is right up against the top portion of the firewall covered up by the intake plenum.
How long did you take to do this the first time and what should a person expect to spend to get this done by a pro. ? It’s a lot of pieces to take apart. Ugh. I don’t even have one of those fancy ratchets. Well put together video all the same very good.
@@hardlymovingpro To avoid the confusion (to the newbie like me), the replaced sensor in this video should be call A/F sensor (instead of O2 sensor). It took me a while to figure it out. Thanks again.
Maybe for the plenum but not the throttle body since the gasket is metal. The plenum gaskets looked like they were in good shape. The important thing is to make sure the contact surface (intake manifold) for the plenum gasket is clean. You can coat the gasket with silicon grease before connecting and bolting down the plenum to the intake manifold.
you need to download the "check engine" DTC (diagnostic trouble codes). If you don't have a code reader, you can get a free download at any auto parts retailer. They come out, hook you up and print out the codes. From there you can figure out what needs to be done.
Thanks for sharing the process. I'm in Australia and the owns a equivalent model of 2009 Aurion V6 with 150k. Recently changed spark plugs in order to tackle the rising fuel consumption level (near 20L/100km). I used ODB2 scanner to monitor two pre-cat oxygen sensors and noticed their voltage stay around 3.3v. Are they likely failing without any error code showing up? Cheers
I have experienced cars with O2 sensors getting "lazy" enough to make the car run sluggish but not trigger a mil code. With the milage you have on the car, I'd replace them. Replace with either Denso or NGK.
I don't know what Toyota calls it but BMW calls a it an intake manifold actuator which controls the flow of air based on either engine load, rpm's or both. Believe an internal air direction plate permits either a short or long air path, within the plenum, into the intake manifold resulting optimum power for the rpm range. Traditionally, engines with long plenums give greater low rpm power; shorter plenums for high rpm power; this device, I believe, works as a compensator giving you both. Clever engineering when it works.
Can this job be done by just removing the cowl assembly and the bracket that's over the one coil pack, my hands are pretty small thinking I can fit them back there.
Thanks for the video. This 2GR-FE 3.5L engine has much less room to work on than 1MZ-FE 3.0L. With an OEM O2 sensor cost $200-300, I wouldn't replace if it doesn't fail. I would spend time to clean throttle instead.
When the O2 sensor goes bad, you've got no choice but to replace the sensor. Your car's PCM will ignore the erratic O2 sensor signals but will allow you to operate your car with an over rich air/fuel mixture. The rich air/fuel mixture prevents the car from a potential over lean air/fuel mixture which can overheat and damage the engine. The over rich mixture will results in a drop in fuel efficiency and within a few months burn out your catalytic converters. The burn out is caused by excess hydrocarbons (unburned fuel) being burned by your cats. The excess heat eventually destroys the converters. When your check-engine or MIL goes on because of the O2 sensor, and the longer you ignore it, the sooner you'll burn out your cats. So if you think O2 sensors are expensive, check out the cost of a new cat on these cars. You can buy new OEM Denso sensors for a little over $100 at Rockauto.com.
You're sort of right. One easy repair procedure is usually offset with another procedure which can be unusually difficult and expensive ... like replacing worn out axle shaft U joints or malfunctioning transfer case that your FJ has but the Camry doesn't.
The bracket is difficult to see by eye. You have know where it is and feel for it. The 13:07 time mark shows where the bracket is attached to the plenum.
Might sound dumb but im having the worst luck removing the o2 season bank 1 sensor (closest to firewall) all my tools hit the wall or just impossible. Any specific tools you use that made it work.
This is a turnoff for owning a Camry v6. I managed to change the spark plugs in 1999 Camry v6: other than a broken wire, all went fine. But this 06 Camry v6 and 6 hours? No way.
As I become more experienced the Camry V6 gets less daunting as when I started. One component waiting to be replaced is the rear engine mount that is bolt together with CV axle. I hesitate to take out the axle just to replace the engine mount. I might use polyurethane to glue the broken rubber.
@@hardlymovingpro Thanks for your advice. I have already had the replacement part. From testing the gear change between R and D, I can tell the rear motor mount is bad. But I haven't sensed other symptoms during drive (except occasional clunking noise when I brake that may or may not relate to this). Back to the topic of Camry V6 vs I4 preference, I4 offers more space in general but can also be a PITA with a bad design. For example, changing PCV my 2010 Camry (2AR-FE) falls into that bucket. Others have reported 8 hours amount of work changing that small part.
That's a 3/8" hex socket attached to a 3/8" socket wrench used to removed the hex bolts that hold down the intake plenum. Can't recall the specific hex size but you can usually by a hex socket set for under $10.
Great Work. Did you have to reset the throttle? I changed the spark plugs out of a Nissan, and afterward the idle acted weird. I had to reprogram it. Do I need to reprogram the idle with a Toyota? Thank You. I have a 2007 2GRFE engine.
The tricky thing about Nissan's is when cleaning the throttle body, do not move the throttle plate. If you do, then yes, you have to re-program. Haven't run into Toyota's with the same problem with electronic throttle bodies.
That's correct. They're push pin pliers and that's a tool I use a lot. The tool is only around $10 or less. Unlike needle nose pliers, the tips are designed to "pinch" which helps tremendously removing these plastic electrical connectors. The trick is learning not to pinch too hard or you'll brake the plastic.
They're called push pin pliers. Here's a link to Amazon: amzn.to/2Bo2DIx You can also use fuel line clip disconnect pliers. Here's the link: amzn.to/2MeU0lp
If not replacing the plugs, use a long handle 19 mm box wrench. Come in from the driver's side firewall. Remove the air filter box and plenum brackets to make more room if you want.
@@hardlymovingpro Thanks! I struggled to get it because of how reduce the room was. But I went to O Reily's and they had a shorter socket with the ratchet insert offset to the side, so I was able to dig in with the torque wrench and bust it out! A long process but feel proud to have done it all myself.
@@hardlymovingpro my gf Camry is having hard start every morning but it turns all the time. I'm thinking it's the sp. Her car dad 92k miles. What symptoms were u getting? 150k miles is allot lol
I use a thin tip metal pic tool and place it between the clip and the clip retainer. The clip is then lifted off the retainer and the electrical fitting pulled.
@@hardlymovingpro Thank u so much for your reply & I really appreciate it. I'll go and buy push pin removal tool . Pls advise which brand & model you recommend .
Hello thank you for this video. Thinking of doing this soon. Can I just replace the spark plugs or do I have to replace the coil packs as well? I have a 07Avalon. 199k on it but I got it used @123k miles. Everyone says To go with oem Coils but they aren’t cheap lol.
If you're dealing with a cylinder misfire code specific to a particular cylinder (P0301 - P0306), replace the coil pack for that cylinder. If no misfire codes, don't replace it.
@@MICHAELWALTON1 That's correct. The left most bracket should be removed. It gets in the way of the 2nd bracket upper bolt. The 2nd bracket can stay on loosely by loosening the lower bolt.
@@hardlymovingpro I wanted to give an update on my spark plugs exchange on my 2GR-FE engine in my 2007 Lexus es350. As demonstrated at the 2:45 mark of the video, the drain cowling wasn't bolted on but welded on. A dagger in my heart! Just not enough room for me and my hands to work on plenum bolts. I didn't even get the wiring harness loosened. So after my best effort, I buttoned every thing back down, but lubed wiper motor assembly with white lithium, cleaned the throttle body and plate (filthy) & cleaned the wiper blade with denatured alcohol. It was an learning experience. ? do you get to the left plenum bolt from underneath the car ? Your assessment, please? Thanks
In the absence of design flaws, poor quality control or manufacturing defects, 4 cylinder engines, because of less moving parts, should have fewer problems. From 2002 to 2006, the head bolt threads in the Camry's 2AZ-FE's block might strip. The only fix is to remove the cylinder head and insert steel Time Serts ... an expensive and time consuming solution. If the dealers are asking over $1,500 for the repair, might as well get a re-manufactured engine.
Nice Job! I'll do the same for my 2010 Lexus ES350 which have the same engine as the Camry. My questions is: It is necessary to do an Idle relearn procedure after you remove the battery and clean the throttle body (moving the plate)? Thank you and again excellent job!
If a Nissan TB plate has been moved ... yes ... but believe Toyota's are more forgiving. To play it safe, avoid moving the throttle plate all together. Disconnecting and re-connecting the battery won't require a relearn.
I'm thinking about getting myself a 2009-2010 Camry. I've heard the l4 engine has issues with the piston rings. Does that make de V6 a better option, or does this car have similar problems? Thanks guys!
@@hardlymovingpro Wow!! Thanks for answering, I really appreciate it. I think that such reliability is worth a couple miles to the gallon, so I'll look for a nice V6 one.
If you are changing your spark plugs in your Lexus ES350 you dont need to remove the wipers and motors. Lexus has a bigger engine bay than Toyota but the engine is the same. Also removing on bolt from the intake brackets on each side would be enough. I didnt have to remove the strut bolts and the bar as well. I did mine this way and worked perfect although this job is pain in the butt anyway.
As you said "this job is a pain in the butt". It would have been easier if you removed the wiper motor cowling. Using my electric impact tool, spinning off those 10 mm bolts to remove the cowling takes up a few minutes of my time.
I was given a qoute for $725 for just the spark plugs and a gasket replacement for the manifold. They said it was that expensive becuase of over 3 hours in labor, is that how long it should take?
You only replaced one O2 sensor which I suppose goes bad much sooner than the others, mind did. How long do the other o2 sensors last by your experience? Thanks
I treat O2 sensors like spark plugs ... which, by the way, easily last over 100k miles. If the sensor is easy to get to, I generally leave it alone. I make the exception to replace it when I realize how ridiculously difficult it may be to replace if or when it fails. On the Camry, Avalon and ES350 with the 2GR-FE engine, the right bank sensor plug is butted right up against the firewall below the wiper cowling and behind the intake plenum. Also, the sensor wire is alligator clipped it. Good luck getting your hand in there and unplugging it! I figure a repair shop might charge up to 3 hrs labor to replace it. So take the hit and replace it while it's easy to get to, or wait till it fails? You're choice.
@@hardlymovingpro Thank you! My car is at 160 k miles . I had the spark plugs replaced around 90k mark. So next time i do my plugs ill do the other 3 sensors. Hopefully a little cheaper to change when doing the plugs? Great video by the way!
Just finished doing this job 🥵 Definitely took me about 6 hours to complete and all the locking tabs on electrical connectors to my coil packs broke 😢 Any recommendations for securing them down other than replacing the whole connector?
Not unusual for the tabs to break off. Happens all the time. Easy solution is to apply a light coat of RTV on the coil pack's slide on contact surface where it meets the connector.
It would be difficult to disconnect the O2 sensor's plug connected to the upper portion of the firewall. Perhap just remove the windshield wiper cowling.
Nope. Someone else also had the same concern a few months back. The spark plug ground strap is dropping into the spark plug hole and therefore cannot be damaged.
There is an exhaust leak noise coming from the back of my canary v6 motor,, I checked the flex pipe, it's not that it seems to be closer upfront,,, i cant see behind where its coming from,,, does the exhaust manifold usually have problems on this car or could it be the gasket connecting flex pipe to the manifold,,,, I'm hoping this is an easy fix.. motor is running ok tho no codes..
Check the exhaust pipe connection points for leaks. Some may be spring loaded with a flexible "donut" type seal that allows both pipes to slightly bend against each other. The donut seal is a wear item and could be the cause of your noise.
After completing the job I’m getting a CEL p0365 p0014 and p0017. Summary after changing the plugs I had to disconnect one of the crankshaft position sensor to make some room for #5 coil pack I did the whole job nice and clean. Put everything back together the way it suppose to be. Start the car I got CEL code p0365 I erase the code thinking i disconnect the camshaft sensor may be that’s why I took the car for a spin CEL came back on but the code was 0014 p0017. These codes stayed if I would erase them they would come back after few miles.( never had any issue before ever) today I change bank 1 sensor B. But codes still not cleared sesame story started again p0365 follow with p0014 and p0017. I check all the electric connection for corroded or damage wires everything looks good. Please let me know what should I do next or where I’m making a mistake.
I'm going to guess that the electrical connector (the one you unplugged to make room) has somehow been damaged. With a volt/ohm meter, you'll have to do a electrical continuity check on the connector. With the plug disconnected and the engine off, use something like a paper clip to join the electrical connection between the female connection points in the plug. Pierce each of the wires going into the plug, connect you volt/ohm wires and perform the test. If the meter does not sound off, you've got a electrical break somewhere. Wiggle the lead until you hear a good connection. You may have to replace the connector.
Thanks for replying. I forgot to mention one more thing which I want to mention now please let me know if that would make a difference or if it will bring these codes. While I was taking out cylinder number 1 coil pack the rubber boot got stuck into ceramic part of the plug I went through a lot taking it out since not enough room. I got the boot out and clean it off with air, a very tiny price half or quarter size of the penny was left inside I took the plug out thinking it would come out with it but it didn’t come out and fall off inside the whole. I put the new plugs gap and torque them. The car runs fine no misfire or anything like that. But these codes are coming on my scanner. I wonder if that small price of rubber have something to do with these code since its fall on top of the piston. I am very concern about this issue and we don’t have any good mechanics who I can trust they are just part replacer no proper Diagnose. I would really appreciate you reply back. Thanks
Great thanks that was my biggest concern. I’m getting p0017 which is for bank 1 sensor B, which one will be the sensor B on that motor? The one near cyl 1 or cyl 5? Thanks
Yup ... bank 1 sensor 1 is the oxygen (aka air fuel ratio) sensor need replacement. You're lucky. It's the manifold by the radiator. Firewall is bank 2.
Just used this video to change all 6 spark plugs on my 08 Camry SE. I just paused it at each step so I would get lost. Sadly, I didn’t have my engine coils so I’ll have to redo all this to change those 🥲
Clogged fuel injectors. Had someone replace both plugs and coils on a Honda accord. Still kept misfiring. Did a pressurized injector cleaning service via the fuel line. Completely fixed the problem.

@@hardlymovingpro Dang...brilliant. I wanted to do the coil/plug swap test to isolate but I dont know why I was thinking I would swap it with 3 or 5...but then I'd have to put it all back together, test, and then do it all again. Dumb :) Your way obviously simpler. Haha. Thanks, man! Take care!

Excellent!! Thanks
You bet!
Great video and very well explained, you are awesome!!!
Thanks and appreciate your post!
Thanks for your video its helpful
Glad it was helpful!
excellent. Im about to start on my 02 toyota camry v6
Excellent! Good luck!
I think after a few more times viewing your video I'll jump into the deep end and do this myself this weekend. Thank you so much for the useful information! I do have one question, what is the gap measurement for the spark plugs?
The new iridium plugs should come pre-gaped.
Really nicely done video!
Thanks for you comment and support!
Great video I’m looking to do this job as well I already have all the parts I just wanted to know which o2 sensor is the upstream left and upstream right?
They're both the same except for the length of the sensor wires. Some manufacturers keep them long so they are interchangeable between the left and right.
For me, a little over 3 hours. If doing it for the first time, give yourself 6 hrs.
Are the sensors under the car? I see a lift being used in other videos
If you're asking about the O2 sensor I'm replacing in the video, it's screwed into the top portion of the exhaust manifold below the firewall. The hard part is getting to the O2 plug which is right up against the top portion of the firewall covered up by the intake plenum.
@@hardlymovingpro thank you!😀
No problem!
How long did you take to do this the first time and what should a person expect to spend to get this done by a pro. ? It’s a lot of pieces to take apart. Ugh. I don’t even have one of those fancy ratchets. Well put together video all the same very good.
Give yourself around 6 hours
Bravo. Love this.
Thanks!
@@hardlymovingpro To avoid the confusion (to the newbie like me), the replaced sensor in this video should be call A/F sensor (instead of O2 sensor). It took me a while to figure it out. Thanks again.
Yikes! This is more involved than a Odyssey with a V6. Thanks once again for your descriptive and informative videos 👍
Glad you liked it!
This is the v6 you idiot.
When you do this, do you put new plenum and throttle body gaskets? Thanks.
Maybe for the plenum but not the throttle body since the gasket is metal. The plenum gaskets looked like they were in good shape. The important thing is to make sure the contact surface (intake manifold) for the plenum gasket is clean. You can coat the gasket with silicon grease before connecting and bolting down the plenum to the intake manifold.
Awesome video! Keep up the great work - really enjoyed the pacing. What size as your Milwaukee racket, 1/4” or 3/8”?
3/8 and 1/2. The 1/2 gives me 60 lbs of torque!
did you replace upstream or downstream o2 sensor?
upstream.
I have a Camry 2008 xle and I have all lights on if I change the O2 sensor will that help me? Also Is it a similar engine?
you need to download the "check engine" DTC (diagnostic trouble codes). If you don't have a code reader, you can get a free download at any auto parts retailer. They come out, hook you up and print out the codes. From there you can figure out what needs to be done.
Hi there, am I going to be able to take the O2 sensor by taking the top part of the wiper blades tray without taking the top of the motor off ?
Reach in from under the throttle body/intake plenium.
@@hardlymovingpro I mean would it be enough space to reach the sensor without taking the top of the engine and throttle off ?
Thanks for sharing the process.
I'm in Australia and the owns a equivalent model of 2009 Aurion V6 with 150k.
Recently changed spark plugs in order to tackle the rising fuel consumption level (near 20L/100km).
I used ODB2 scanner to monitor two pre-cat oxygen sensors and noticed their voltage stay around 3.3v.
Are they likely failing without any error code showing up?
Cheers
I have experienced cars with O2 sensors getting "lazy" enough to make the car run sluggish but not trigger a mil code. With the milage you have on the car, I'd replace them. Replace with either Denso or NGK.
What is the name of the hose at 10:10?
PCV (Positive Crankcase Ventilation). There's one on each bank.
at 9:26 that exact electrical fitting with the white housing was disconnected on mine when i was filling my washer fluid. What is that sensor for?
I don't know what Toyota calls it but BMW calls a it an intake manifold actuator which controls the flow of air based on either engine load, rpm's or both. Believe an internal air direction plate permits either a short or long air path, within the plenum, into the intake manifold resulting optimum power for the rpm range. Traditionally, engines with long plenums give greater low rpm power; shorter plenums for high rpm power; this device, I believe, works as a compensator giving you both. Clever engineering when it works.
Hardly Moving Productions thanks! Really informative video by the way👍🏼
@@ShreddinBullets1 Glad you found it useful!
Did you need to replace the manifold gasket ?
I've found that in most cases the intake plenum gasket can be reused without leaking.
Great video 👍🏼
Thanks!
Can this job be done by just removing the cowl assembly and the bracket that's over the one coil pack, my hands are pretty small thinking I can fit them back there.
You might have problems getting out the #6 coil pack (right rear).
Were you able to do it without removing the plenum
@@pardesi_life yes it's kinda tight but have plenty of light and use a mirror
Thanks for the video. This 2GR-FE 3.5L engine has much less room to work on than 1MZ-FE 3.0L. With an OEM O2 sensor cost $200-300, I wouldn't replace if it doesn't fail. I would spend time to clean throttle instead.
When the O2 sensor goes bad, you've got no choice but to replace the sensor. Your car's PCM will ignore the erratic O2 sensor signals but will allow you to operate your car with an over rich air/fuel mixture. The rich air/fuel mixture prevents the car from a potential over lean air/fuel mixture which can overheat and damage the engine. The over rich mixture will results in a drop in fuel efficiency and within a few months burn out your catalytic converters. The burn out is caused by excess hydrocarbons (unburned fuel) being burned by your cats. The excess heat eventually destroys the converters. When your check-engine or MIL goes on because of the O2 sensor, and the longer you ignore it, the sooner you'll burn out your cats. So if you think O2 sensors are expensive, check out the cost of a new cat on these cars. You can buy new OEM Denso sensors for a little over $100 at Rockauto.com.
Hardly Moving Productions I really like your detailed how-to videos! Keep up the great work!

What is the model number of the Milwaukee power wrench you're using in the video? Would you recommend it?
A link to all the tools used in the video should be in the description area of this video.
Just subscribed. Man the 4 cyl much easier lol. I have that v6 09 Camry.
Yes ... the 4 cylinders are much easier.
I'm glad my FJ V-6 is mounted straight on...
You're sort of right. One easy repair procedure is usually offset with another procedure which can be unusually difficult and expensive ... like replacing worn out axle shaft U joints or malfunctioning transfer case that your FJ has but the Camry doesn't.
I couldn't see the plenum bracket that you were talking about in the first portion is there a way you could get a better pic of it?
The bracket is difficult to see by eye. You have know where it is and feel for it. The 13:07 time mark shows where the bracket is attached to the plenum.
Any tips on how to remove the electrical connection for the downstream o2 sensor? Its cramp!
I hear ya! Suggest going to a local muffler shop with the part in hand. They should do it for cheap. Don't go full service repair shop.
@@hardlymovingpro thank you so much for the tips!! you have helped me a lot with my 2gfre engine. i donated a small tip. again, thanks for everything!
You bet and appreciate your donation to the channel!
Might sound dumb but im having the worst luck removing the o2 season bank 1 sensor (closest to firewall) all my tools hit the wall or just impossible. Any specific tools you use that made it work.
I've used a long handled box wrench.
@@hardlymovingpro tried and no luck. Starting to think its stuck on there good
This is a turnoff for owning a Camry v6. I managed to change the spark plugs in 1999 Camry v6: other than a broken wire, all went fine. But this 06 Camry v6 and 6 hours? No way.
I've worked on both and didn't find the 06 that much more difficult
I guess like everything else. The proper tools make it easier I guess.
As I become more experienced the Camry V6 gets less daunting as when I started. One component waiting to be replaced is the rear engine mount that is bolt together with CV axle. I hesitate to take out the axle just to replace the engine mount. I might use polyurethane to glue the broken rubber.
If it's broken, I'd replace it.
@@hardlymovingpro Thanks for your advice. I have already had the replacement part. From testing the gear change between R and D, I can tell the rear motor mount is bad. But I haven't sensed other symptoms during drive (except occasional clunking noise when I brake that may or may not relate to this).
Back to the topic of Camry V6 vs I4 preference, I4 offers more space in general but can also be a PITA with a bad design. For example, changing PCV my 2010 Camry (2AR-FE) falls into that bucket. Others have reported 8 hours amount of work changing that small part.
great job!
Thanks for the visit!
What tool is being used at 3:51? I can’t seem to find the name anywhere
That's a 3/8" hex socket attached to a 3/8" socket wrench used to removed the hex bolts that hold down the intake plenum. Can't recall the specific hex size but you can usually by a hex socket set for under $10.
hex sockets dude
Great Work. Did you have to reset the throttle? I changed the spark plugs out of a Nissan, and afterward the idle acted weird. I had to reprogram it. Do I need to reprogram the idle with a Toyota?
Thank You. I have a 2007 2GRFE engine.
The tricky thing about Nissan's is when cleaning the throttle body, do not move the throttle plate. If you do, then yes, you have to re-program. Haven't run into Toyota's with the same problem with electronic throttle bodies.
what type of pliers did you use to assist with the wiring harness removals ?? .. they look like push pin pliers ??
That's correct. They're push pin pliers and that's a tool I use a lot. The tool is only around $10 or less. Unlike needle nose pliers, the tips are designed to "pinch" which helps tremendously removing these plastic electrical connectors. The trick is learning not to pinch too hard or you'll brake the plastic.
Awesome video! I have a question how long did it take you to complete this entire job?
Around 3 hours or less.
Where did you get those TWO Pliers from that you used to remove the electrical connectors ?
They're called push pin pliers. Here's a link to Amazon: amzn.to/2Bo2DIx
You can also use fuel line clip disconnect pliers. Here's the link: amzn.to/2MeU0lp
How do you get the o2 sensor out if it's stuck? Little room to work back there and it seems a swivel socket isn't enough.
If not replacing the plugs, use a long handle 19 mm box wrench. Come in from the driver's side firewall. Remove the air filter box and plenum brackets to make more room if you want.
@@hardlymovingpro Thanks! I struggled to get it because of how reduce the room was. But I went to O Reily's and they had a shorter socket with the ratchet insert offset to the side, so I was able to dig in with the torque wrench and bust it out! A long process but feel proud to have done it all myself.
Good for you!
Nice job

Is this the same for a 2008 highlander, also is the sensor you changed considered bank 1 or 2? Thanks
Yes. the 2008 - 2016 Highlander uses the 2GR-FE 3.5L V6 engine.
The sensor by the firewall is bank 1, sensor 1. Also, Toyota calls the upstream O2 sensor an air/fuel ratio sensor.
Thanks 👍
Hello thank you for this video. Thinking of doing this soon. Can I just replace the spark plugs or do I have to replace the coil packs as well? I have a 07Avalon. 199k on it but I got it used @123k miles. Everyone says To go with oem Coils but they aren’t cheap lol.
If you're dealing with a cylinder misfire code specific to a particular cylinder (P0301 - P0306), replace the coil pack for that cylinder. If no misfire codes, don't replace it.
Would it be possible to remove the rear spark plugs with only removing that windshield cowl and not the intake manifold?
Possible but would be tedious ... IMHO
@@hardlymovingpro Thanks for the advice. What about removing only the manifold, throttle body, and air box?
Whatever works for you. With me if I spend too much time and effort trying to get something off, I take off whatever is in the way.
great video
Thanks!
On the plenum brackets bolts is removing just top bolts each side to remove doable?
On left driver's side the bolt brackets might get in your way
@@hardlymovingpro okay i noticed you completely removed the left side and only top bolt on right, so i'll do it your way, np thx
@@MICHAELWALTON1 That's correct. The left most bracket should be removed. It gets in the way of the 2nd bracket upper bolt. The 2nd bracket can stay on loosely by loosening the lower bolt.
@@hardlymovingpro I wanted to give an update on my spark plugs exchange on my 2GR-FE engine in my 2007 Lexus es350. As demonstrated at the 2:45 mark of the video, the drain cowling wasn't bolted on but welded on. A dagger in my heart! Just not enough room for me and my hands to work on plenum bolts. I didn't even get the wiring harness loosened. So after my best effort, I buttoned every thing back down, but lubed wiper motor assembly with white lithium, cleaned the throttle body and plate (filthy) & cleaned the wiper blade with denatured alcohol. It was an learning experience. ? do you get to the left plenum bolt from underneath the car ? Your assessment, please? Thanks
I'm confused. You couldn't get the wiper motor cowling off because it's welded on?

Yes ... the difference would be minor.

Was wondering if the V6 motors have fewer problems than the 4 cylinder 2AZ-FE's? I know Toyota had some issues w/ the head bolt threads.
In the absence of design flaws, poor quality control or manufacturing defects, 4 cylinder engines, because of less moving parts, should have fewer problems. From 2002 to 2006, the head bolt threads in the Camry's 2AZ-FE's block might strip. The only fix is to remove the cylinder head and insert steel Time Serts ... an expensive and time consuming solution. If the dealers are asking over $1,500 for the repair, might as well get a re-manufactured engine.
Is it same process for 2010 lexus es350?
Yes. The ES350 uses the 3.5 liter 2GR-FE engine.
Nice Job! I'll do the same for my 2010 Lexus ES350 which have the same engine as the Camry. My questions is: It is necessary to do an Idle relearn procedure after you remove the battery and clean the throttle body (moving the plate)? Thank you and again excellent job!
If a Nissan TB plate has been moved ... yes ... but believe Toyota's are more forgiving. To play it safe, avoid moving the throttle plate all together. Disconnecting and re-connecting the battery won't require a relearn.
I'm thinking about getting myself a 2009-2010 Camry. I've heard the l4 engine has issues with the piston rings. Does that make de V6 a better option, or does this car have similar problems? Thanks guys!
The V6 is a rock solid motor. Won't give the same fuel economy of an I4
@@hardlymovingpro Wow!! Thanks for answering, I really appreciate it. I think that such reliability is worth a couple miles to the gallon, so I'll look for a nice V6 one.
Thanks
Welcome
If you are changing your spark plugs in your Lexus ES350 you dont need to remove the wipers and motors. Lexus has a bigger engine bay than Toyota but the engine is the same. Also removing on bolt from the intake brackets on each side would be enough. I didnt have to remove the strut bolts and the bar as well. I did mine this way and worked perfect although this job is pain in the butt anyway.
As you said "this job is a pain in the butt". It would have been easier if you removed the wiper motor cowling. Using my electric impact tool, spinning off those 10 mm bolts to remove the cowling takes up a few minutes of my time.
Would that be the upstream o2 sensor or the downstream??
Upstream. Downstream is behind the converters.
I was given a qoute for $725 for just the spark plugs and a gasket replacement for the manifold. They said it was that expensive becuase of over 3 hours in labor, is that how long it should take?
I can do it in around 2 hours. No need to replace any gasket.
Now I know why you suggest replacing the senser when replacing the plugs. Ngk or nippendenso?
My preference is Denso (aka ND or Nippon Denso).
You only replaced one O2 sensor which I suppose goes bad much sooner than the others, mind did.
How long do the other o2 sensors last by your experience? Thanks
I treat O2 sensors like spark plugs ... which, by the way, easily last over 100k miles. If the sensor is easy to get to, I generally leave it alone. I make the exception to replace it when I realize how ridiculously difficult it may be to replace if or when it fails. On the Camry, Avalon and ES350 with the 2GR-FE engine, the right bank sensor plug is butted right up against the firewall below the wiper cowling and behind the intake plenum. Also, the sensor wire is alligator clipped it. Good luck getting your hand in there and unplugging it! I figure a repair shop might charge up to 3 hrs labor to replace it. So take the hit and replace it while it's easy to get to, or wait till it fails? You're choice.
@@hardlymovingpro Thank you! My car is at 160 k miles . I had the spark plugs replaced around 90k mark. So next time i do my plugs ill do the other 3 sensors. Hopefully a little cheaper to change when doing the plugs?
Great video by the way!
@@sandeepp6300 If the sensors last that long.
@@hardlymovingpro Got it! might do the plugs a little earlier
Just finished doing this job 🥵 Definitely took me about 6 hours to complete and all the locking tabs on electrical connectors to my coil packs broke 😢 Any recommendations for securing them down other than replacing the whole connector?
Not unusual for the tabs to break off. Happens all the time. Easy solution is to apply a light coat of RTV on the coil pack's slide on contact surface where it meets the connector.
is it possible to change the o2 sensor without removing everything?
It would be difficult to disconnect the O2 sensor's plug connected to the upper portion of the firewall. Perhap just remove the windshield wiper cowling.
Aren't you risking damaging or changing the gaps by dropping the new spark plugs in like that?
Nope. Someone else also had the same concern a few months back. The spark plug ground strap is dropping into the spark plug hole and therefore cannot be damaged.
@@hardlymovingpro Makes sense. It would be hard to have the center piece touch the wall since it's a cylindrical shape.
There is an exhaust leak noise coming from the back of my canary v6 motor,, I checked the flex pipe, it's not that it seems to be closer upfront,,, i cant see behind where its coming from,,, does the exhaust manifold usually have problems on this car or could it be the gasket connecting flex pipe to the manifold,,,, I'm hoping this is an easy fix.. motor is running ok tho no codes..
Check the exhaust pipe connection points for leaks. Some may be spring loaded with a flexible "donut" type seal that allows both pipes to slightly bend against each other. The donut seal is a wear item and could be the cause of your noise.
Hardly Moving Productions thanks will do
I just did this job last week, I did not remove any of the Cowling.
Whatever works.

great video!
After completing the job I’m getting a CEL p0365 p0014 and p0017. Summary after changing the plugs I had to disconnect one of the crankshaft position sensor to make some room for #5 coil pack I did the whole job nice and clean. Put everything back together the way it suppose to be. Start the car I got CEL code p0365 I erase the code thinking i disconnect the camshaft sensor may be that’s why I took the car for a spin CEL came back on but the code was 0014 p0017. These codes stayed if I would erase them they would come back after few miles.( never had any issue before ever) today I change bank 1 sensor B. But codes still not cleared sesame story started again p0365 follow with p0014 and p0017.
I check all the electric connection for corroded or damage wires everything looks good. Please let me know what should I do next or where I’m making a mistake.
I'm going to guess that the electrical connector (the one you unplugged to make room) has somehow been damaged. With a volt/ohm meter, you'll have to do a electrical continuity check on the connector. With the plug disconnected and the engine off, use something like a paper clip to join the electrical connection between the female connection points in the plug. Pierce each of the wires going into the plug, connect you volt/ohm wires and perform the test. If the meter does not sound off, you've got a electrical break somewhere. Wiggle the lead until you hear a good connection. You may have to replace the connector.
Thanks for replying. I forgot to mention one more thing which I want to mention now please let me know if that would make a difference or if it will bring these codes.
While I was taking out cylinder number 1 coil pack the rubber boot got stuck into ceramic part of the plug I went through a lot taking it out since not enough room. I got the boot out and clean it off with air, a very tiny price half or quarter size of the penny was left inside I took the plug out thinking it would come out with it but it didn’t come out and fall off inside the whole. I put the new plugs gap and torque them. The car runs fine no misfire or anything like that. But these codes are coming on my scanner. I wonder if that small price of rubber have something to do with these code since its fall on top of the piston. I am very concern about this issue and we don’t have any good mechanics who I can trust they are just part replacer no proper Diagnose. I would really appreciate you reply back.
Thanks
@@786variety Don't think that would set off the error codes you've been getting.
