P0171 Cadillac ATS PCV Hose Replacement
ฝัง
- เผยแพร่เมื่อ 17 ต.ค. 2024
- Got another check engine light on my 2013 Cadillac ATS 2.0T. This time is is the P0171 Lean code. In this case it is caused by a couple of huge splits in a plastic PCV line. This seems to be the same hose that is used on other LTG applications such as the Camaro.
The part I used was 12673868.

Thank you for this video. I was changing the spark plugs on my 2018 ATS and noticed the same exact crack on the PCV tube that’s been causing the car to burn a lot of fuel. Ordered the part today from the GM direct online store. Appreciate you👍🏼
Happy to help. Hope it goes on easy. While you are checking things under the hood, check the "Y" shaped hose going into your coolant bottle. Mine got a crack on the bottom of the piece where the "Y" is and caused all kinds of trouble because it was dripping on my ECU.
@@HoldMyBeverage ok I’ll check it out thx
@@HoldMyBeverage yea mines crack too before and almost had engine running hot hey what’s that other hose beside pcv hose called??? that’s crack too the one connected to top part of engine
Does that make your engine shake ?
@@amoney31aplus28did ever find out what the name of that other hose connection is, because I'm still looking for that answer.
What you changed was the pcv TUBE. The pcv VALVE is on the top of the engine right infront of the coil closest to the windshield connected to the tube right next to the pcv Tube that you changed. Over time, just how your pcv tube had cracks, the inner part of the pcv Valve thats directly in the engine gets corroded or chips away which makes the engine performance bad. Change the pcv valve and youll see major engine improvement. Helps it breathe alot better. Pcv valve part # is 12637666. Pcv tube part # is 12673868.
Thank you. If I said I replaced the valve, I misspoke. I did not mean to give the impression that I did.
@@HoldMyBeverage its alright. Super easy to mix all the pcv names up. Just wanted to clarify for all your viewers!
@@NN2PX8 much appreciated. I'd hate to give people incorrect information.
I believe you told it right.
You said hose. Maybe he heard you wrong.
Is there a video on pcv r&r? I have a 2018 XTS and I smell oil burning after highway driving... average speed on highway 70 to 80 mph
Cadillac Dealership Was Trying To Charge Me $500 To Fix Mine. I Did It With Your Video And The PCV Tube For $80. Thanx For The Video!!!
Glad I could help!
Crazy Ahh dealers should be arrest
Dude, you saved me a major fucking headache! I'm a wholesale auto dealer and was getting ready to take my ATS4 into the dealership that was 2 weeks out on appointments. You're the best guy on TH-cam!
That is great to hear! Thank you so much!
@@HoldMyBeverage it was exactly the same at every spot. Thanks again!
@@OutlawChevy2 my pleasure!
Omg thank you Jesus man I’ve been contemplating about going to the dealership I seen this video and seen a crack the exact same pcv hose wow now I can finally fix it get this code off my Cadillac ats 👏🏾 🙌
I hope it does the trick for you.
@@HoldMyBeverage hey what’s the name of that other hose beside the crack one u showed that’s crack too it goes to top???
@@amoney31aplus28 I'm not completely sure since it seems like the previous owner had already replaced it, but I'm pretty sure that one runs right into a PCV valve. It would seem to be another PCV hose. Take a look at part number 12681589. That may be the one you are referencing.
What's the part number for the hose you replaced? This video was super HELPFULL! Just can't find the hose lol.
@@philipfields5450 it's at the end of the video description. For some reason I can't seem to copy it on my phone, or I would have just replied with it.
Great Video, helped me out with my CODE P0171. I replaced the Air fliter, MAF, and the cleaned the bara sensor, still didnt fix the issue. Long and behold the PCV hose.
I'm glad it did the trick!
Great video I saw the leak didn’t think much of it now I have a check engine light.
Thank you. I hope a new tube does the trick for you.
Had the code and like everyone else, found this video then discovered the same cracked hose. Of course, the part isn’t available at the moment so I used the new “toy” I just got three days ago. A plastic welder. First time I used it and it paid for itself on the first job!
Glad to hear you had a way to fix it. I might have to look into one of those.
Super helpful, very thankful! The new connections will need a fuel line tool to remove, if anyones curious
Glad to help. Thank you for the clarification on the tool needed for the new connections.
True. However, the connection closest to the front of the engine does not allow enough room to get a fuel line tool in for removal. That one took two picks for me to get it off. There's no reason why these hoses should be this poorly designed. Do better GM. Same with the Y coolant overflow hose. Those like to leak at the Y fitting and it's just poor design.
Same here. took off the cover and there it was. Thing is I had my 2014 CTS to the CADILLAC Dealership for this exact trouble code. They were kind enough to find other things but NOTHING regarding the REAL PROBLEM. Pretty hard to miss and pretty common it seems. 300 in diagnostics later plus, plus.
That is terribly frustrating.
I’m Dealing with the same thing right now took it in for the same exact Job that they diagnosed and once the part came in and they called and said another code showed up and the part was Around $20 but where it was located would take three hours to replace the cooling sensor and is an additional $380 i labor on top of the $350 for the original job cooling sensor behind the engine that is supposably keeping the fan on
Thanks dude! once this code popped up i had no idea what the problem could be. after watching the video i went and checked that hose and sure enough had a crack right where it T's off at. ordered the part and a 6 day shipping est. gonna try to tape it and see if that will hold up til the hose arrives.
I hope it does the trick for you.
@@HoldMyBeverage one question if you don't mind answering. once you taped the cracks in the tubing, did the check engine light go away instantly?
@@dogsofwar9030 no. It was probably the next day.
@@HoldMyBeverage thanks bud. it was the problem.
Thanks for the video. My tube was cracked and like you used electrical tape to get things going until the part came in.
Where did you order it from
that intro deserves a sub
My '15 ATS w 62k has the code....cleaned the MAF, air filter...those expensive hoses look good, so I may clean or replace the PVC valve. It seems my code pops with a half empty gas tank. 🤔
Interesting. I hope you get to the bottom of it without much more trouble. Mine will still pop the code occasionally when I have idled the car for a long time, say a half hour to an hour. It doesn't come on then, but comes on the next time I start my car. I don't do that frequently, but with children in multiple after school programs, I occasionally find myself a half hour from home just sitting there waiting for them while they are taking part in their activity.
Damn, kinda seems like all these engines get loud eventually? My ex 2.5L 2014 ATS eventually got this loud, my 2018 2.0T CTS is very quiet, hoping it doesn’t turn this loud 🙉
What are the plastic circles that will go inside there to unplug it? I saw it on another video but I forgot what they are called
@@axellopez5206 try searching fuel line disconnect tool.
Great video, so I replaced both pipe and I still got the same problem, the code is P0171 System too lean bank 1, any help will be appreciated thank you.
Thank you. Unfortunately, I don't have any other suggestions. I hope you get it sorted out.
Did you fix it? Im in the same boat
Hi! Thanks! I have p0365 camshaft position sensor b circut bank 1. Any advice? Couls it be a result of the dirty air coming in and can be cleaned? Any advice please!
Check if your coolant is leaking from the y hose going from the radiator to the reservoir. It leaks right down onto the ECU and will cause that code as well as crank shaft position sensor. Cause so many codes for me and was a pain to track down.
@@HoldMyBeverageI had to change that Y hose a few months ago. I think you'd think the coolant would have burned off/evaporated by now , but worth a check. Thanks!
@@ThePudgie123 it probably has evaporated, but it causes corrosion that can create lasting issues. I have a video of how I tried to remove my corrosion. It seems to have worked well in my case.
Thank you. Fixed my problem.
That is great! Glad it helped.
What is the name of the other hose connection, higher up on the engine, it too is running from the engine to the turbo?????
I believe that is also a PCV hose or tube as well. I haven't looked for that one though, so I cannot say for certain.
Thanks for this video what was the seize of the range that you use to untire the bolt need to do this on my vehicle
The bolt was 10mm.
That’s awesome man!!!
Thank you
Thank you, super helpful
You're welcome! Always glad to hear when my silly videos help a bit.
thank you very much sir i hope this fixes my problem same code same issue so wish me luck
@@twizted420o best of luck to you. I hope it fixes your issue!
Great Video, But I think you need to change your oil....
Oil changes have all been done on time and with appropriate oil since I purchased the car. I got it with around 30k on it and the valves have always been loud. I'm guessing the valve tick is why you are saying I need the oil changed.
I did end up getting the valve cover gasket replaced after this video. I never really thought much about it, but I think the car may be quieter now. Makes me wonder if the old one was seeping enough to cause lower levels of oil on the valves than there should have been.
Have the exact same crack on mine lol .
Good video 💪
Thanks. I hope it helps.
@@HoldMyBeverage got it done
What's the other hose that looks same but skinner than this hose nd connected to turbo?? Top of this hose
@@gagan4123 I'm not sure, but is it part 12681589?
The crankcase ventilation tube.
Mine cracked im trying to figure out how to remove it. They’re on eBay if you need one
Thanks for the video broski
You are quite welcome.
Good job!!
@@larryh811 thank you!
I noticed the new one has a different way to get it off what tool is that called? I purchased one for my car and I couldn’t get it off
I have not had to remove one yet, but from what I've seen, you might want to look at fuel line disconnect tools. I am not 100% sure if that is the right thing.
Upgrade your ats pcv system with a oil catch can. The can will come with new hoses and you will also protect your motor fro oil blow by.
Send me a video please of the can installation
Hows is your work holding up?
I havent had anymore difficulty with this part. Excuse me while I go find something wooden to knock on...
Bro starts off drinking a milk jug from his kids lunchbox. 😂😂
Valley Cadillac in Rochester NY replaced 2 of them on my '13 under warrenty.
That is great! Did you have an extended warranty? Even if those are on powertrain, mine ran out long ago.
@@HoldMyBeverage Mine was done under the usual warrenty, but I only had 5 days left on it.
I wish I would have seen this yesterday. Cost me just she of $300 to have the dealer fix it. They had just changed the ignition coils last week. My guess is they cracked the tube while doing it.
Dang, that stinks. I wish you had seen it too. That hose seems to be pretty brittle. I think it is common for them to be cracked.
My hose just split as well. Thanks for the video. Do you have the part number?
Double check that it fits your year and engine, but I believe it is 12673868
While you are at it, check that the "Y" in the coolant return line going to your coolant bottle is not leaking. That thing cost me so much time and money. Keep an eye on dang thing.
@@HoldMyBeverage Thank you! Just ordered the new part. I did check the Y coolant return piece and it looks to be in good shape. I've been keeping an eye on that as it seems like a lot of other people have had that issue.
@@buldan8 not sure how much of the video you watched, but check if your hose uses the same type of latch I had on my old one, or if it is like the new one. If its like the new one, I believe you need a fuel line disconnect tool.
@@HoldMyBeverage Part came in today and I replaced it in under 10 minutes thanks to your video. Very helpful. Appreciate it!
Did this to my 13 ATS a few years ago
Thank you! I got that code, I can do that!
I hope it helps. Check to see if you have the cracks before replacing the hose. This is a likely culprit, but there could be other reasons you may get the code.
Thank you
You're welcome. Hope it helps.
How did u take off the old plastic tubing from the valve nipples, to replace it with the rubber hose on the single line thsts mostly metal?
Mines cracked at the metal end and I don't want to break the plastic connector end because that side of the plastic hose is still intact
@@richardcordeo8586 the rubber hose was put on by a previous owner. Models of the car newer than mine require a special tool to remove the hoses. I think it is a fuel line removal tool. They look like a semi circle that you put around the house and slide. I have not used one, but the replacement hose I put on in this video requires one to remove it
Thank you so much brother!!
I changed it but the code keep appearing again and again even though I don’t see any leaks and cracks in new pcv ! What to do? But the car is driving fine
Did you check the other hose beside it? Seems that one can have issues as well. I think it had already been replaced on my car when I got it.
@@HoldMyBeverage i checked that hose too, that one looked good with no cracks or leaks ! Any more suggestions? Thank you
@@gagan4123 unfortunately I am not a mechanic, so my knowledge is limited. It is possible that the valve itself needs replaced.
@@HoldMyBeverage okay so i found the leakage on the tube which connects the air filter ! Now my question is was there supposed to be little bit oil or not ! Leakage was from the other end of the tube, not from the air filter side !!
@@gagan4123 oil in there seems to be normal for this type of engine. Search for Cadillac ATS catch can. You'll find products that basically replace the PCV tubes and add in a can that catches the oil. There is debate over whether it is a problem, but apparently it can coat your valves in that crud you are seeing and basically bake on causing trouble down the road. This is pretty much a standard problem with direct injected engines. If you want to learn more, try searching for direct injection valve coking.
Can you show a fuel rail sensor location?
I'm sorry. I really do not know where that is, and honestly I wouldn't touch the fuel rail on these things. That is beyond my comfort level. These direct injected engines run so much pressure that the rail can be quite dangerous if you don't know what you are doing. I dont know what im doing lol.
Thank you for the reply haha I completely understand! I appreciate the honesty and help !
Whats the part number on that tube? You remember?
It is at the bottom of the video description. Sorry, I cannot seem to copy it to paste it here.
What’s link where I can buy these Jose I have a Cadillac CTS and I have the same issue can you please help
I am not sure if this would necessarily fit the CTS. What year and engine do you have?
@@HoldMyBeverage thanks for answering and it’s a 2014 2.0 very similar to the ats
@@ivannambo5583 unfortunately it is out of stock where I got it from. This one seems to list your car as compatible. I am not a mechanic. I am just reading what it lists as compatible.

Would the car idle funny when stoped at a light...?
Like wanna shut off
@@carlosvalenzuela22cv mine did not. Are you getting a check engine light? If so have you ran the code(s)?
@K Q I went through a lot of those symptoms on mine because a coolant line was leaking on the ECU. Thats rough that you've been through several engines.
Where did you get the part from? I’m having the same issue
I dont recall, but it looks like GM Parts Direct has it. www.gmpartsdirect.com/oem-parts/gm-pcv-tube-12673868
Just upgrade and get a catch can and run silicone hoses and also protect your motor from oil blow by.
The slightest crack can throw a code?
I don't know. Mine was substantial.
Thanks alot!!!
Happy to help.
Where did you order the part from
I can't recall if I got it from gmpartsdirect.com or a dealership. Im guessing gm parts direct because it is usually much cheaper.
Alright thank you 🙏
Where did you get the part and how much did it cost.?
I don't recall, but it may have been gmpartsstore.com. I believe it was around $70, but that was a while ago.
Did it clear the code by its self since you replaced it
@@miltondavila9470 it did, but I think it may have taken a day.
Was stabilitrak service showing for you sorry for the questions
@@miltondavila9470 ohhhh, I did have that one, but I think that was related to a larger issue that I had with coolant leaking onto my ECU. I have a video on that too. I highly recommend checking the "Y" in the hose going to the coolant reservoir. That caused so many lights and issues with my car. It is the video that starts with "check engine light P0340.." if you want to check that one out.
Oh I forgot did you need a tool to bend it so it could reach were. It needed to
I did not. It was already the appropriate size and shape.
Thanks for the video have the same car and code this will help a lot also have a code of P06de have you had this one before?
I have not had that one. Looks like that is something with the engine oil pressure control circuit.
This may be completely unrelated, but I had several codes that were throwing for different sensors and found that the "Y" shaped hose running into the coolant reservoir was leaking onto my ECU causing electrical issues. Probably not your problem, but its an easy thing to check. I have a video somewhere about that too.
What is the part number?
The part I used was 12673868. I have added it to the description for the video now. Sorry that it was not already there for you.
Thanks for the great info another thing to check out on the car it just started today been doing some major testing, mine has the p0171 code and p228c wich would low fuel pressure but i checked it and it has the normal 850psi so just checking dumb shit now before i start checking for wiring problems. I like your vid but do me a favor and throw that fuck pos all in 1 wrench in the trash before you strip bolts😂 just my 2 cents
I hope you get it figured out.
You’re awesome dude thank you
Thank you! You're welcome. I hope it helped.
Thanks for the info and video
My pleasure. I hope it was helpful.
