Kick ass video right on. I had a 6.2L LS in an Escalade kept throwing p0172 p0175 I spent $ bank on new scan tool new brake booster new hoses new intake manifold gaskets new throttle body new MAF new IAT new PCV 4 new o2 sensors new exhaust gaskets the left valve cover BS etc. ITS LIKE I WAS CHASING A GHOST. Everyone said it was my aftermarket intake. I refused to give up. It would show good data and then after a week or a few days codes and 85% alcohol running like crap. Saw the video. Tested the purge solenoid after 3 to 4 opens it leaked. BINGO! $40 part and trims settled, running better every day. PURGE SOLS DO INTERMITTENTLY FAIL HUGE VAC LEAK. THIS GUY IS A LIFE SAVER A+ THANKS AGAIN
Evap Service Bay Test... ( on scan tool )... i'm glad you showed this after replacing part ! I used to just replace part and hope fer the best ... not anymore ! Great video !
I like your video because it provided me with alternate test. I was getting the codes that had displayed. I swapped the O2 sensors, TB and MAF sensor. Right now my truck is running good but I am burning a lot of fuel. I did not look at the purge valve or the Charcoal cannister. I will take a a look that this weekend. Thank you and keep posting videos.
AWESOME you are the best, I have a 2002 Dodge ram and spent 2500.00 to NOT fix the issue. I have done most of the work with great videos with advice from true mechanics like you! I have a PO172 code with PO455 and PO442 and was thinking that there has to be an issue making me get other codes also. (That other mechanics didn't think of) I'm going to change my purge valve and gas cap and see what happens maybe even the Valve on the charcoal canister to be safe. Thanks for the great video and scan tool!
Thanks for the great comment 👍. When ever I get multiple codes I always take a few minutes to look into if they can be related somehow. Let me know how that works out for you. I really enjoy it when I see my videos help people.
This is great info! I have an 03 Ranger 4x4 with 250,000 miles on it and it's basically giving the same codes except mine is rich bank one, and evap system small leak. It has the 4.0 engine in it and this is the third video I've seen on different models including Ford. I think this might be the problem. I've replaced several sensors as well as changing fluids like transfer case, diff, oil, and just dropped the trans pan changed the filter and filled it back up, I did not flush it...to afraid to but I do plan on dropping the pan every year and repeating the process or maybe every other year. The transmissions on that Ranger has like 18 bolts on the pressure plate once you drop the pan and they are only supposed to be torqued at like 7 pounds so they all come loose, it was having a little problem shifting into overdrive until I crisscrossed tightened the bolts on that plate back to spec and it's perfect now. So many times it's something simple, not every time but don't assume the worst right away. One thing can lead to scores of other things. Thanks for the video, I'll be getting a new purge valve soon and see if that works. It's the original with over 250k on it and not that expensive and easy to get to with similar codes so why wouldn't I start with something that doesn't even require a jack to replace.
@@shanersmechaniclife3164 I have the purge valve on order and I'm betting that's it because she runs down the road just fine but terrible mpg. I forget the YT name, it was one of many when I did my trans fluid change but he was the only one who pointed out those bolts when you pull the pan. I think there are 12 or 18 of them at about 7-8 ft. lbs torque and every single one was loose. Start in the middle and crisscross your way to each end and it helped the 3-4 automatic gear change....maybe I should have put some blue locktite on them but I didn't want to ruin it, I don't know how ATF and blue locktite gets along. When it gets warm again, I plan on dropping the pan for an aftermarket one with a drain plug and I will inspect them then, if they are loose, I'll but blue on them and let them set before adding fluid. Thanks for the videos!
I have a 04 GMC Jimmy 4.3L. At idle, once warmed. The MAF is reading 8-9g/s. Replaced it with a new one and still same readings. I’m having a p0101, P0172/175 Banks 1&2 rich. The fuel trims show a -25 LFTRsx I replaced the spider injection thinking it was a leaking regulator/injector and still no luck. O2 sensors 1 fluctuate normally. Bank 2 shows kinda high. .6-.7ish. Not sure what can be causing the high MAF reading. I’m thinking a bad IAC and maybe a bad Purge valve
Hi Shane, I am getting the P0172 on a BMW 3 series 2017. I have changed the Upstream O2 sensor how that has not worked fault code re apeared. I have a basic Scan tool and I can see Fuel Level input is 93%. STFT Bank 1 is : -1.56% LTFT Bank 1 is: - 17.19% Oxygen sensor bank 2 Bnk 1 Voltage 0.77V Not sure if any of the above helps. But if you have any ideas or if mine can be Rurge Valve or HPFP. any help. Thanks.
We have rich codes on bank 1 snd bank 2 for a long time on 2012 ford focus 1.6l The dealership asked us to replace spark plugs several times but the problem continued, then they kept saying it just needs programming but after a couple of days it comes back.. Unfortunately we are out of warranty right now I did injectors cleaning with chemicals twice, and it shouldn’t be the O2 sensors since it’s unlikely that both have failed at the same time Is something like the purge valve or the PCV more likely to be the cause of these codes?
If it's a 2012 with original o2 sensors i would probably replace them. They are a maintenance type item and tend to slow down as they age. Do you happen to know what your fuel trim numbers are? If it's a flex fuel vehicle try resetting your alcohol sensor. Hope this helps. Let me know what you find. Thanks for watching
@@shanersmechaniclife3164 I asked a friend to borrow his OBD II scanner and I’ll have a look at the fuel trims and tell you what I find The code came several years ago since the car was still under warranty but we ignored it after the dealer failed to fix it several times and they gave us the impression that it was not a big deal, so at the time the car probably had less than 35k miles on it, now 64k, which makes me doubt that both O2 sensors failed so early at the same time Plus when I recently asked about their price it was something like 300-400$ each so it’s really expensive! I’m used to 80-90$ in our other cars so hoping that they’re fine The car uses petrol/gasoline only and it has a similar engine to the Fiesta in the US, a 1.6l petrol, so we fill it with 95 or rarely 91 petrol

Good idea checking basics like bolt torque. Let me know how it works for you. Thanks for the compliment!

I cleaned MAF, throttle body and replaced the air filter too btw

Thanks so much for this video I was having a challenge of acode p2188-00 fuel trim rich idle is a Chevrolet Cruze 2012
Great informative video
Glad you liked the video. I try to give as much info as possible and keep the video a reasonable length. Thanks for watching.
Thanks for the info. This helps me a ton!
Glad it helped you. Thanks for the comment and for watching.
How can I test that solenoid without having that scanner
You can't sad to say
Great video ❤ thank you for sharing
Thanks for watching and the great comment. Whenever I get multiple codes I always check to see if they all have something in common. Are there any videos you think youtube needs more of? I'm always looking for ideas.
Cool video I have no scann tool but now I have an idea what's wrong. Thank you!
p0172,p1450 ford focus se 2016
I replaced the purge valve and i still have these codes, I have no idea
The engine is just revving on its own
It revs on start up? To red line?
Very helpful thank you
Solid tip
I've seen one issue cause multiple troublecodes often.
Good info bro,
Appreciate it. Thanks for watching and commenting.
Mines don't say bank 1 or 2 jus says rich with the code tho so should I jus change both
Have you figured out your problem yet? Do you have evap codes or just rich codes?
Great vid, 🙌
Thank you! Thanks for watching and commenting.
I am having issues with fuel consumption.
Hope you find the fix for your problem. What fault codes do you have after your previous repairs?
Good shit my boi
Glad you found my video helpfull I'm glad you liked it.
So my canister on my 2004 f250 5.4l 2v is non existent
