For over a year now I have been struggling with this cruze 2011 turbo. It had other codes at the beginning but I am mainly stuck with P1101.

I have replaced the PCV valve, map and maf sensors, the PCV hose, the car is still shaking when coming to a stop, and also when removing the oil dipstick

Can you elaborate by what you mean when you say replaced the PCV valve?

Check out this article as it pertains to that error code: https://www.cruzetalk.com/threads/2011-2016-cruze-1-4l-pcv-system-explained.175793/

There are two actually PCV valves...

P1101: MAF Out of Self Test Range
Chevrolet Cruze P1101 Trouble Code

P1101 is one of the most common of the Chevy Cruze trouble codes. Whenever you start the vehicle, the mass airflow sensor does a self diagnostic. If the results of this test are out of range, than the P1101 trouble code is thrown.

There are a number of issues that can cause the mass air flow sensor to fail the diagnostic. We鈥檒l list them in the most to least likely to have happened.

Chevy Cruze P1101 Causes
Engine Wiring鈥 A good place to start is to do an inspection of the area around where the mass airflow sensor plugs into the intake. Make sure that the wiring doesn鈥檛 look broken or disconnected. You鈥檇 be surprised, in the winter months a rodent can cause a lot of damage to a an engine in one night.

Air Filter鈥 Pull your air filter and see if something has gotten in there. If it has, remove the debris. Or if the filter looks very dirty go ahead and replace it. If enough air is not getting into the engine the mass airflow sensor is not going to get a proper reading, and P1101 will likely be thrown.

If neither the engine wiring or the air filter seems to be a problem, then it鈥檚 going to be time to pull the mass airflow sensor and see if it is dirty. A word of caution, these sensors can be incredibly sensitive to the oil鈥檚 on skin so make sure to use caution and not touch the sensor element itself.

Leaking Intake鈥 If the intake seal on the Chevy Cruze has been damaged, there鈥檒l be a vacuum leak. A vacuum leak means that air will be getting in to the intake not through the throttle. This is going to dramatically alter the reading at the mass airflow sensor gets and will trigger P1101.

A mechanic would be able to do something called a smoke test, which would let them visually see where the intake is leaking from.

If you would like to try to find the vacuum leak yourself go ahead and perform a visual inspection and make sure that you don鈥檛 have a disconnected or broken vacuum hose. If it looks ok, than carb and choke cleaner can help. Here鈥檚 a good video on vacuum leak diagnosis.





MAF Sensor May be Bad鈥 at this point the only cost that we should have incurred is the cost of a can of carb and choke cleaner. If everything checked out, and there were no intake leeks, than it鈥檚 time to evaluate whether the MAF sensor is bad.

Here鈥檚 another YouTube video. This one goes over how to test a MAF sensor with a multi-meter. It鈥檚 relatively easy to do and multi meters are cheap.



Will the P1101 code make the Cruze stop running?
The P1101 code typically will not be enough to make the engine not run. A bad mass air flow sensor is enough to make the engine:

  • Idle poorly
  • Consume more fuel
  • Lose power
If left unchecked, a bad MAF sensor can lead to other engine problems.

I tried checking the purge valve but I cant really see it from the top where I disconnected a hose, I am not sure if it is impossible to see it from there or it actually isn't there. The pcv valve I was referring to is the one on the cap of the engine.

How would we be able to perform a leak test on our own? Just recently bought mine and this is the only code. It comes on and off through the week.
What do you mean leak test? Boost? If you are trying to refer to the PCV valve, Read the link in post #6.

Please see this video, for me it was the positive vent tube 1- way diaphragm that was blown. I only was getting a pending/permanent code of P1011. It could also be your manifold, valve cover or any other vacuum hose in the engine bay (technically). the most common issue I found when researching is to replace the valve cover which houses a PCV vent diaphragm. Video below explains the system and all items he talks about will DEFINITELY fire off a P1101 code and also P0068 code (sometimes) and also others related to air/fuel mixture or calculation. On occasion I saw "poor turbo performance" and sometimes when coming to a stop my engine would approach idle, idle rough then die. This occurred when the purge valve opened and my faulty hose let air into the turbo intake.

Hi have you ever found a fix for the p1101 code? I have a 2014 cruze 1.4 and P1101 is the only code I have been struggling to remove. I have the same symptom. Code comes off and on for over a year. Ive replaced and cleaned many different parts but no luck.

Have you had a look at your check valve inside the intake ? There a common problem but I'd start with going over all vacuum hoses if the car is still running fine with slight drop of revs when idling that's showing a vacuum leak

Has anyone heard of a bad turbo assemble causing this code? My daughter was told that her turbo may need to be replaced to correct the P1101 performance trouble.

I have a 2011 Cruze which I've had since new. My daughter started experiencing performance trouble and was told by OnStar that it had a code P1101. She had the car checked out by the local Chevy dealer and they said that the turbo was most likely the problem but they would need to do more testing to be sure. Has anyone heard of a turbo assemble being the cause of a P1101 fault code? The performance problems she is experiencing seem to be the same as what is being described as PVC and or MAF sensor problem.

Spend a few minutes under the hood and check for yourself. All it entails is carefully removing a hose and looking into the opening to see if the orange silicone poppet like valve is still there. You may need to clean the soot/gunk etc with some cleaner and a tooth brush to see, but it is far cheaper than a turbo.

Hey guys. P1101 came on and I replaced the MAF. Engine light hasn't returned, but the engine is acting noticeably different. Rough idle, hesitation when hitting the gas from a complete stop, and the timing of the shifting it off as well. None of these engine issues were happening before I replaced the sensor. Replaced the turbo about 6 months ago, but the readouts I received didn't have that as a possible solution.

Any thoughts?
