Not as hard as one might think. I had never done it before But after watching a few vids. And stopped being intimidated. With the proper tools Dropping a tranny isn’t that big a deal
@@soundwave802002 I've done it several times. It not too hard when you have a lift and trany jack but when you do it in your drive way or on the side of a dirt road in the dark, it sucks. It also depends on if it real wheel drive- those are easier also. A few bolt around the bell housing, mounting bolt and the driveshaft and it's out. But front wheel, sometimes its easier to pull the whole drive train including motor.
@@soundwave802002 bro u have no idea if you havnt actually done it. Watching videos and seeing exactly how to do it won’t mean it’s easy. For starters the transmission is heavy asfuc especially if it still has the tranny fluid inside. 2nd of all you have to dissemble multiple components before you think abt dropping the tranny. And most of the time these bolt are seized such as the drive shaft bolts. I guess you can say the easy part is disassembling every thing and dropping the tranny. The real hard part is putting everything back to place and at it’s respectable specs. I had trouble just tryna get the bell housing aligned and back into the engine, it’s not just a one easy push and bam. Every bolt has a specific torque and if you strip any bolts you’re fuked.
Great video. They don't make old school mechanics anymore. Most guys just want to scan and replace. You helped you me out after my car going to multiple garages. Keep up the good work!
Thanks Thomas! Well done. I recently did the rear main seal and the exhaust manifold gaskets on my '02 BMW. I then got lean codes for all 4 Oxygen Sensors and Signal issues to the ECU. Turns out it was almost exactly the same issue. I must have pinched the harness when raising and lowering the engine and transmission. It actually cause a Transmission Failsafe Program (Limp Mode) making the car undriveable until I found it. I wish I had watched your video sooner. Keep up the good work and thanks again !
I'm very glad I found your video. I had a problem with my throttle body having no 5v reference, already check the harness for throttle and the pcm connectors, no luck. I almost given up as I already concluded that it is the PCM is the culprit but you gave me hope in your video and with further looking on all the sensors I found out it is my a/c pressure switch wire is chewed by our dog. Right now I am on the way to fixing it, just needed to buy a new connector as our dog chewed it so badly. Cheers!!
Clear explanations and step by step tracing exact from P0135. Impressive and we'll done finding short circuit. Thank you so much it's helps with my same problem too.
I want to say I actually learned something from this video. I have been an automotive electronics tech for 15 years and I never seen this before. Helped me find a draw inside my instrument cluster that would have taken weeks to find without this trick. Thumbs up bro
great news, i too goto youtube. ha sometimes i i google my question and my video pops up from 5-6 years ago, then i remember. hahaha thanks for watching.
I have worked on cars for many years but I have not quite yet figured out how to trace electrical problems down, thank you for this video, I have a 73 c30 Chevy truck with a slow drain on the battery, I will be trying this later in the week, again thank you!
My goodness I admire your determination men, I have the same reading low voltage circuit on my B2 S2 Honda pilot 2008 but you gave me an Idea because when I check my sensor it is still working good 8.7 ohms in reading which is still good
I have the exact same issue and will be doing the exact same thing u did, changed all 4 o2 sensors and all have low voltage code, below a volt, thanks so much very easy to do but pain in the ass, hope my issue isn't dropping the trans, thanks man
I've been wrenching for decades. But I still get impressed by persistent and well oriented work. Well done! I can't stress enough, how important it is to route the cables/harness properly. Recently I wasted a huge amount of time in a certain car. Because some "distracted soul" didn't route the cables properly and exchanged an AC cable/plug. By a not so far oil sensor cable and plug! In spite of the different colors, etc. Among other messy stuff in there! When I properly routed the cables and placed it on the correct supports and brackets/fixing points. Suddenly the overly stretched cable became evident! And the "bling" moment happened! Someone connect the plugs on the wrong places! Beside the AC not working, the oil light still came on at start up (different circuit). The cable was stretched and rubbing on the engine, but thankfully not for long enough to short it! Similar in this case if the harness had been properly routed. Probably the issue wouldn't have happened in the first place! ;-)
Great video, explains clearly how to identify any electrical problem on your vehicle! Helped me find the problem on my 5.7 2011 Dodge Ram 2500. All four O2 sensors were pulling codes so I knew it had to be the ground or power. (Only thing that would affect all four sensors at the same time) Couldn't be the power or other functions of the truck would not work.... like fuel pump. (If I understand correctly.) Dealer did a bunch of work that didn't touch the problem. I decided that it had to be a ground and traced it out to an extremely frayed woven (shoe-lace) ground cable. Two thumbs up!
I know you posted this comment over a year ago, but do you remember where this frayed ground shoelace cable was located? Recently had my motor 5.7 rebuilt and ever since I got the truck back it shows the codes for low voltage on 02 sensors and when the truck gets up to running temp it will lock on 1,000 rpm once I hit a bump in the road. Any help on this will be great.
@@fishingdfdubb2807 The frayed shoe-lace ground was on the passanger side near the door and front wheel well. I later found a wire on top of the bell housing where the O2 wires crossed the housing that needed to be insulated. When my motor was rebuilt they did not protect the wire and it rubbed a bare spot and would contact and gave me fits to try and find.
Wow nice work and great video, this is the kind of video that shows exactly what happens when you're persistent and problem solve the crap out of an issue. Tip of the hat to you, man. I had all four O2 sensors binging low voltage every once in a while and since they were fairly new OEM sensors and it would go away after a few trips I knew they couldn't be the issue so I chalked it up to the CAI and lead foot. But then it came back and stayed so I was racking my brain as to where I should start on a 20 year old truck with 250k mile. Recently had my engine and trans lowered so a fresh oil pan could be installed (Chrysler/Dodge sure did a number when they used the 4.7 for so many different makes and models, solid performing engine but not every vehicle was thoughtfully designed around it.) I was worried I might be in the same situation as you and was not looking forward to dropping the trans and hunting though the wiring harness there. Already had the trans rebuilt by a mechanic that really knows their stuff. So I started with a visual check of the wiring I could see without removing anything. Then onto checking all the grounds, and bingo was his name-o. Found one braided ground strap hanging on by a thread that the engineers thought running it right over the left cat converter to the chassis was 'smart'. Ran a fresh ground wire one on that side from the chassis to a bolt on the engine. Then found a second braided ground strap going from the muffler/exhaust chassis that was again hanging on by a thread at the bolt on the muffler/exhaust, you couldn't tell by just looking at it but the second I grabbed on it just started to crumble. Ran a fresh one there too after cleaning the surfaces and muffler bolt for good measure. Reconnected the battery and after several trips to complete the trucks computer tests, it appears that this has remedied the issue. Guess I got lucky. Moral of the story, for anyone having issues with an engine light and all four o2 sensors showing low voltage or intermittent electrical issues... Check your battery connections and then check those grounds. Even if they are intact they may be on their way out. Some grounds may be hard to find on some vehicles, so research your vehicle and where all the grounds are supposed to be.
Electrical issues are super confusing to me. Plus the way my brain is wired i could read and read. And my brain can’t grasp a lot of what’s going on. I watched countless videos of people doing amd trying to explain this method. But they all pull 2 fuses amd find the issue right away. I been pretty discouraged. Having pulled fuses once twice and again only to have the light come on. Then i find your video and my brain finally grasp the issue. I still haven’t found that damn short. But now i know. I just have to keep pulling what i can get to. Untill it goes out I’m confident I’m gonna find it tomorrow. I love my 94 S10 blazer 4.3L Vortec. But she has never ran great. But i managed to keep improving things. But your video really gave me confidence. And i already learned how to take the trannys out a couple years ago. Amd with the proper set up and tools. It’s easy Looking forward to watching your other videos. Keep up the good work brother!!
Super good info! I recently hsd my vehicle dyno tuner and under load the front O2 sensor reading drops. The tuner said it is either a bad O2 sensor or bad ground. I think it would be a safe bet that it is in the ground. Plus the engine was just rebuilt. I just hope I don’t have to hunt my short down into the transmission harness.
Too cool! Thanks for inspiring me! I have a 04 4.7 Dakota put all bran new O2 sensors on it. My mechanic found the O2 sensor fuse gets no juice gonna look today where u said it was
Long old school process, BUT! you found it man!! Cheers,, Have to pull alot of stuff anyway to repair wire harness! Great job, now service your trans while out..lol
Man going through it right now with a Nissan Frontier. I’ve paid four different mechanics and none of them have fixed the problem. So I finally decided to take matters into my own hands… I’ve completely gutted the inside of the truck dash and all. The engine compartment is next! 😮I’m gonna find and fix the problem and that’s a promise! And also a big Thanks to you good sir. Without your knowledge/ guidance I never would’ve mustered up the courage to tackle on such a task. Thank you 🙏
@@anunentitledmotivatedmille7731 I discovered a faulty ignition switch. But the major culprit was a bad alternator plug. It would cause the truck to not charge. Therefore I was running off just battery.
I have low voltage in my Bank 2 downstream 02 sensor. I don’t know where to start. Does each sensor have a ground wire/cable that is bolted down on the CAT? Could it be a fuse to that specific sensor? It’s a 2008 Nissan Frontier SE V6 4.0L. Any advise would be appreciated.
@@davechambers5279 Disclaimer not a professional by any means lol. But I would, start at the plug and work my way back. Sometimes connectors go bad or become corroded. Test the end of the plug then move up a foot or so and test the wire itself. If the voltage differs, then the plug/ connector could be the issue.
Hey man, I don’t know if you read these comments. But I want to personally thank you for this technique you showed us for finding the short. As soon as I connected the probe test light to the disconnected positive terminal it faintly lit and then I heard a little erratic buzzing in and out noise, traced the very faint sound to the brake light switch. When I jiggled the switch the light went off, and as you would let it be for a min the light would come back. The switch is faulty. That explains my no cruise control and intermittent TCC lockup (seems like an rpm surge, tcc struggles to stay locked) But anyways thank you, this crap was driving me crazy. My truck is 98 C1500 (Silverado) ext cab. Fleetside 5.7l Vortec L31
Savage! Hahaaa.. Great video dude right on👍 my first time ever subscribing someone's video. I don't even really know what that means but u deserved it buddy much appreciated!🤘😎
Thnx this made me decide not to buy a new O2 sensor that did not work anymore because I was so stupid to clean all connectors and now I have a lot of problem with all the sensors and stuf thnx bro
Ha!! Thanks! You gave me an idea 💡 see I would only pull the fuses the light never went out till this day! Now!! I know what to do!... Ps my truck hasn’t ran for five months now!
Thanks for the inspiration; I am searching down a heater circuit code using this method. I have to rule out the pcm yet, I think it’s in the harness, which guess what.. is right between the transmission and the cab of my truck lol!
Appreciate much your first video on finding shorts (a gem) But here, wait a sec..... you had to drop the transmission to find bad wire? Oh my..... This went from being a simple diy project to a non-starter. Glad you had the skill to make it work for you, but wow..... (kinda like telling the average joe how to change out the back three spark plugs on the dreaded Venture/Montana/Silhouette...... not for the feint of heart)
Best jump scare I’ve had in a long time! 😂 I’m having circuit faults on 3 out of 4 sensors (which are new and ohm test fine). I’m hoping I find the problem before I have to resort to major surgery.
@@shawnalexander1158 I have not, unfortunately. I suspect it’s a tuning problem, but I’m hesitant to spend the $ only to have them tell me they can’t figure it out either. Car drives fine otherwise. Just a pesky CEL that I’d feel better having fixed.
Reach up and feel on top the bell housing for two wires. When you find them video them with your phone and look for bare spots. Tape them individually and then together if they have a bare spot. This is where my problem was. When my motor was rebuilt the wires were not supported and left to rub in the bell housing. It was a sob to find.
I have a p0102 on a 2009 2500 hd silverado I put an LS3 into. And the 5 volt signal voltage to the ground wire on the MAF harness measures 12 volts. But measures 5 volts to ground on the battery
Towards the end where u described about the wire and unplugging the trans, when u grab the wires, under your hand is two blue wires, is one cut or is it showing some copper, right under hand
Did you use the scanner to fine a DTC in the SRS or ABS some times there is a code for battery with a low charge that makes the 02 sensors to fail. Usually it shows with a bank1 DTC keep in mind 02 sensors works sending links of ground.
I'm getting p0036 and p0136 codes in my 2013 sonata. Dealership said o2 sensors are testing good and are blaming the pcm. I noticed chew wires at one of the ignition coils harness. I will strip those wires back and see if that gets rid of the codes.
I gotta try this. I have 2 Impalas, ones an '03, the other is a '00, both have negative o2 sensor readings on bank 1 sensor 1and I'm having a hard time finding any info on it. Thanks for the video, very informative. Just out of curiosity, when I hook a scan tool up to them, are both o2 sensors supposed to read the same? I don't have a really good scan tool, it'll test the sensors, but it only gives me a certain percentage of the sensor readings. Bank 1 sensor 2 reads 99%, bank 1 sensor 1 varies from .00% to -1.25%, sometimes more. I've tried replacing them, I've used cheap ones, I've used expensive ones and I'm still not getting anywhere.
Excellent video, I have a mercedes ml320 it has a fuse box on the inside when I pulled the instrument cluster fuse the light went out. Now I have to figure out how to track it down from there. Thanks I'm no mechanic
Having P100, P505 code that won't reset even after cleaning IAC, TB, MAP sensor plus EF13 fuse keep on blowing at start up, it iddle fine for a mins then it rattle & die, I did the test light while pulling fuses one at a time & two fuses turned off test light which is belong to Radios & dome light but it didn't turn off when I pulled EF13 but it blow each time. Run fine prior washing the back of the engine due to minor oil leak that I'm trying to trace. 2001 Rav4...also noticed one of lower O2 wire was rubbing on timing belt pulley but no damage on wire. What u think the problem?
Wow that's so much work good you have found the problem, my question is toyota sienna 2004 code is p2238 02 sensor positive current control circuit low Bank 1 sensor 1 Is that bank 1 02 sensor located under intake beneath the the wipers ? Thank you and all the best 👌 👍
My jaw dropped when he said, "I had to drop the transmission to find it." and so did my heart. I said unto myself, "Yeah, I'm not doing that."

Thnx this made me decide not to buy a new O2 sensor that did not work anymore because I was so stupid to clean all connectors and now I have a lot of problem with all the sensors and stuf thnx bro
JUST AWESOME EXPLANATIONS
Thanks....great find
Awesome video dude. I’m in the process of playing whackamole hunting the ghost in my 88 Chevy K1500. I’m at the same point. Tracing wires.
That's amazing man !!!
Ha!! Thanks! You gave me an idea 💡 see I would only pull the fuses the light never went out till this day! Now!! I know what to do!... Ps my truck hasn’t ran for five months now!
A lot of work bro…but I’m glad you got it
Great video
Great job bro
Thanks for the inspiration; I am searching down a heater circuit code using this method. I have to rule out the pcm yet, I think it’s in the harness, which guess what.. is right between the transmission and the cab of my truck lol!
Great vid..👍
Oh my god u are freaking badass!:)) TY.
Appreciate much your first video on finding shorts (a gem) But here, wait a sec..... you had to drop the transmission to find bad wire? Oh my..... This went from being a simple diy project to a non-starter. Glad you had the skill to make it work for you, but wow..... (kinda like telling the average joe how to change out the back three spark plugs on the dreaded Venture/Montana/Silhouette...... not for the feint of heart)
ps, still, learned much here from you, yet again. thanks.
Great video.
thanks for watching
Best jump scare I’ve had in a long time! 😂 I’m having circuit faults on 3 out of 4 sensors (which are new and ohm test fine). I’m hoping I find the problem before I have to resort to major surgery.
hahaha thanks for watching
Did u find your problem?
@@shawnalexander1158 I have not, unfortunately. I suspect it’s a tuning problem, but I’m hesitant to spend the $ only to have them tell me they can’t figure it out either. Car drives fine otherwise. Just a pesky CEL that I’d feel better having fixed.
Thank you...il try it on my toyota corolla 4afe...
Wow!.i think im having this issue.thanks.
Good job
I was going to say this guy must really like that truck
Reach up and feel on top the bell housing for two wires. When you find them video them with your phone and look for bare spots. Tape them individually and then together if they have a bare spot. This is where my problem was. When my motor was rebuilt the wires were not supported and left to rub in the bell housing. It was a sob to find.
thank very much
I have a p0102 on a 2009 2500 hd silverado I put an LS3 into. And the 5 volt signal voltage to the ground wire on the MAF harness measures 12 volts. But measures 5 volts to ground on the battery
Perfect Please post one on tracking down pcm input signals and shorts, Like "Begin Here". Thx
Best video I ever seen! 😂 I can’t stop laughing. Welp the trans us out. 👍
BTW, A GREAT VIDEO!!
That’s was a beautiful!
Towards the end where u described about the wire and unplugging the trans, when u grab the wires, under your hand is two blue wires, is one cut or is it showing some copper, right under hand
Did you use the scanner to fine a DTC in the SRS or ABS some times there is a code for battery with a low charge that makes the 02 sensors to fail. Usually it shows with a bank1 DTC keep in mind 02 sensors works sending links of ground.
I'm getting p0036 and p0136 codes in my 2013 sonata. Dealership said o2 sensors are testing good and are blaming the pcm. I noticed chew wires at one of the ignition coils harness. I will strip those wires back and see if that gets rid of the codes.
I gotta try this. I have 2 Impalas, ones an '03, the other is a '00, both have negative o2 sensor readings on bank 1 sensor 1and I'm having a hard time finding any info on it. Thanks for the video, very informative. Just out of curiosity, when I hook a scan tool up to them, are both o2 sensors supposed to read the same? I don't have a really good scan tool, it'll test the sensors, but it only gives me a certain percentage of the sensor readings. Bank 1 sensor 2 reads 99%, bank 1 sensor 1 varies from .00% to -1.25%, sometimes more. I've tried replacing them, I've used cheap ones, I've used expensive ones and I'm still not getting anywhere.
Goddamn!, hats off to you man, you’re a frigging monster of electric mechanic.
Thanks for sharing this l greatly appreciate it. Like and subscribe 👍🏻.
Crazy!
Beast. 💪👍
Excellent video, I have a mercedes ml320 it has a fuse box on the inside when I pulled the instrument cluster fuse the light went out. Now I have to figure out how to track it down from there. Thanks I'm no mechanic
Great video, currently trying to do diagnosis the same issues and I was wondering were you got the wiring schematics?
He tracked it all down
Having P100, P505 code that won't reset even after cleaning IAC, TB, MAP sensor plus EF13 fuse keep on blowing at start up, it iddle fine for a mins then it rattle & die, I did the test light while pulling fuses one at a time & two fuses turned off test light which is belong to Radios & dome light but it didn't turn off when I pulled EF13 but it blow each time. Run fine prior washing the back of the engine due to minor oil leak that I'm trying to trace. 2001 Rav4...also noticed one of lower O2 wire was rubbing on timing belt pulley but no damage on wire. What u think the problem?
Wow that's so much work good you have found the problem, my question is toyota sienna 2004 code is p2238 02 sensor positive current control circuit low Bank 1 sensor 1
Is that bank 1 02 sensor located under intake beneath the the wipers ?
Thank you and all the best 👌 👍
