MAF Sensor

If in fact the airbox is damaged, try locating one at an LKQ or PickNPull type yard for a reasonable amount to replace it. Otherwise your left with buying a CAI. Do not get an SRI as those do not do you any favors.

Potential causes for P0236 to set are:
Vacuum supply
Pinched, collapsed or broken vacuum lines
Faulty control solenoid
Faulty PCM

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.

I have an issue with the outlet tube clip, it seems to be loose, I do not have enough room to do it without removing the bumper . Is there any video that show how to tie it uphe clip?

This was a good thread. I have been scouring these forums for 4 days trying to find something like this. I have a 2012 1.4T automatic and I recently had the P0236 and P2227 codes thrown and while I was replacing a slightly leaky purge solenoid, I looked all my visible vacuum connections over. I've not been able to locate any issues with them but I did notice my charge air inlet hose coming from the turbo to the intercooler has oil accumulation from past PCV failures(those have been fully addressed) but more concerning was the swelling near the end connection and the connection is HORRIBLY loose. I replaced the MAF sensor today and despite it appearing fine, the car has 220,000 miles. I've had the car since 2013 when it had 26,000. In the past, the car had developed a loud whistle/blowing sound from under the hood under hard boost. I didn't pay any mind to it but recently the noise stopped, the boost performance has dropped off and pretty soon I was having to grab downshifts to pull hills I normally pulled without a sweat. Soon, the DTC light came on and the turbo was not being asked to work. Had to dive down a lot of rabbit holes to try and sort this out. I'd considered replacing the MAP Sensor in the manifold and Boost Temp Sensor in the boost hose upstream from the Throttle Body just because but if a new intercooler hose sorts out my woes, I don't see the need. Thanks to everyone on these forums, I'm beyond impressed with the level of knowledge and experiences being shared! I love my Cruze and don't want to trade it or get rid of it because it's been so reliable and economical to operate.
