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’ll list them in the most to least likely to have happened.

Chevy Cruze P1101 Causes
Engine Wiring– 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’t look broken or disconnected. You’d be surprised, in the winter months a rodent can cause a lot of damage to a an engine in one night.

Air Filter– 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’s 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’s on skin so make sure to use caution and not touch the sensor element itself.

Leaking Intake– If the intake seal on the Chevy Cruze has been damaged, there’ll 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’t have a disconnected or broken vacuum hose. If it looks ok, than carb and choke cleaner can help. Here’s a good video on vacuum leak diagnosis.





MAF Sensor May be Bad– 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’s time to evaluate whether the MAF sensor is bad.

Here’s another YouTube video. This one goes over how to test a MAF sensor with a multi-meter. It’s 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 let me know if you resolve your issue, I'm have the same symptoms and have looked all over the internet and no resolution yet. I have the p1101 and p0171 codes seems to drive fine.
