2011-2015 CHEVY CRUZE ROUGH IDLE FIXED!
CODES P0171 P1101 P0106 FIXED!
PVC VACUUM LEAK DIAGNOSIS AND FIX!
VALVE COVER GASKET REPLACEMENT!
hey guys! In this video we have a 2014 Chevrolet Cruze we just purchased for resale not long ago.. after hooking up my Zurich Z13 OBD II Scanner! (It’s actually been a great scanner for a while now! Reads almost everything on a car!) it had 3 major permanent codes which were:
P0171 - Fuel Trim System Lean
P0106 - Manifold Absolute Pressure (MAP) Sensor Performance
P1101 - Intake Air Flow System Performance
All these codes are related to a vacuum leak. Which means there is air coming in past the MAP sensor. causing faulty reading causing too much air and not enough fuel which in turn will cause your cruze engine to idle rough and possibly stall..
The diagnosis process was us spraying some carb cleaner or water around the valve cover to see if there was any change in idle. But before we even got to perform that test we took the cover off and checked what most people call the PCV valve which is (Positive Crankcase Ventilation System) which was creating a suction where it should be timed and electronically controlled. Clearly that was our problem.
Also checked out our Scanner Live Data readings and the short term fuel trim was reading over 30% which is not good.
Well anyways to keep this description short, we went ahead and ordered a new valve cover for this engine since we can’t replace that part by itself.
Part came in a few days later and here’s how we did it!
Thanks for watching the video!

You are supposed to check the non-return valve in the intake manifold and the check valve in the PCV breather hose as well. If that check valve in the manifold is gone, you're going to be doing this job all over again in about 2 years or so. The instructions that come with the Dorman valve cover tell you that. You should have put RTV sealer in the seams where the head and the timing cover meet. Without that sealer, this valve cover will definitely leak oil. Also the gaskets that come with some of these replacement valve covers are junk. Save yourself another headache and put a new Felpro or other quality gasket on it. Also it's a good idea to check the bolts that hold down the timing chain guide. They work themselves loose. Use loctite and re-tighten if they are loose.

[@melissagunderson5575]

If that check valve in the intake manifold is still there, just really gummed up, would you advise replacing the whole dang intake manifold?

[@gatheringwolves8267]

Also the purge solenoid is known for also causing p1101 and po171, keep an eye on the long term/short term fuel trim with engine on, if the purge is stuck open unplug the connector and see if the fuel trim goes negative, that is also another source of leaks

[@kevinjoanmejiasanche]

This was easy work even for someone like me that don’t know shit about cars. Thanks to guys like you on KZbin lol Gracias bro!

[@melplishka5978]

Just for reference. That big valve on the valve cover is not the pcv valve. The pcv valve is part of the intake manifold. That valve on the cover is actually the vacuum control valve which keeps the vacuum in the engine at 12 - 18 inches of water not mercury. But ya it should not be constantly sucking air. If you have this condition also make sure the pcv valve in the intake hasn’t been sucked out. To check you just have too remove the upper hose that goes from intake to turbo. Look down with flash lite. You should see a rubber nipple. If that nipple is gone then you need intake assembly as well.and the vacuum valve of course is complete with valve cover lol.

[@piggyspiddles]

Just subbed up to your channel, just bought a 2015 a year or two ago, really nice little car. But when stopped or in park it sometimes does a slight almost jerk motion like it's skipping or bad gas/old fuel filter type problem. Im not a mechanic, but have no help, so gotta do this myself. Watched this video and I like what youre doing. So Im gonna be watching your videos to help me get some things done on this little car. Do you do Chrysler Town and Country? 2006 model? Ive got one of those as well. Again, not a mechanic, and what I did know, well, I grew up in the 70's and early 80's, so you can imagine what all I DON'T know! LOL Thanks for what you do.

Thanks a lot man it helped a lot pointed me in a right direction that pvc had huge vacuum leak it has set 5 codes o2 , lean code, MAP, Rav to high codeTurbo performance code I fixed that vacuum leak fixed all the problems fixed all codes

[@Roland-Henry]

Replacing the valve cover will only temporarily fix this issue. That check valve on top of the valve cover blows because you're likely missing a small nipple valve located in the manifold. Fix both of these issues at once unless you enjoy buying $60 valve covers every so often.

[@its_Kris]

THIS IS VERY IMPORTANT. YOU MUST ALSO FIX THE CAUSE OF THIS FAILURE OR IT WILL CONTINUE TO HAPPEN. Parts Geek has a kit with the valve cover, intake manifold and troublesome corrugated hose that goes from the top of the intake to the turbo. all for under $250

[@Roland-Henry]

The intake manifold has a small check valve of sorts built into it. This had failed. You don't have to replace the manifold but you must seal the hole off where that nipple valve used to reside then re-route your pcv. Search Cruze fix kit. I didn't but a kit but I watched the video enough I was able to put one together using parts I had and 15 bucks.
