To get it turned off: New seals for oil dipstick, new seal for oil fill cap, cleaned MAF sensor with CRC MAF sensor cleaner, cleaned throttle body with CFC throttle body cleaner, put in new air cleaner. I don't know which one did it, but CEL now off. Dealer wanted 500 dollars to do this and replace MAP sensor. Clearly the sensor replacement (a 10 minute job with 23 dollar part) wasn't necessary as when I did all of the items listed above the light went out and stayed out.

My car was giving me the same code. I replaced MAF sensor, map sensor & air filter. Yet I have cleaned the throttle body. Was your car also having a hard time accelerating and idlining when having your ac on?

Welcome Aboard!(y)

OP basically already answered your question.

Possible causes for P1101
-Faulty Mass Air Flow Sensor
- Air leak before or after sensor
-Mass Air Flow Sensor harness is open or shorted
-Mass Air Flow Sensor circuit poor electrical connection

Read more: P1101 - Mass Air Flow Sensor Out of Self-Test Range

Buy some MAF Cleaner. Amazon.com: CRC 05110 Mass Air Flow Sensor Cleaner - 11 Wt Oz.: Sports & Outdoors and clean it to start off.

Don't forget to introduce yourself and your Cruze here.

I have a 2016 Chevy Cruze LS with 60,000 miles. My OBD 11 scanner gives me one code. P1101. I first changed the filter. The I cleaned the MAF and still no luck. I went to the dealership only to buy a new MAF. Here is the thing. My car runs great. No issues at all. I would like to reset the ECU but I am reluctant because of too many reprogramming issues. I see many people suffer the same issue and I refuse to take it to the dealership. Any help would be great.

2011-2016 Cruze 1.4 PCV Valve Cover/Intake Manifold Issues

The following is all from: Chevy Cruze P1101 and P0171 Trouble Codes | Drivetrain Resource

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 HAD THE SAME CODE. I CLEAN THE TROTTLE BODY AND THE ENGINE LIGHT WENT OFF.

I know a lot of people are dealing with a code P1101 on there chevy cruze. I have a 2016 Chevy Cruze LS. When the light went on, i watch the engine light go on one day and off the next day. Taking my car to the dealership was not a option. I started by changing the air filter with a high end K&N. I took out the MAF sensor and cleaned it and nothing so I did buy one from the the dealership. I had know issues paying $169.00 for it. My next step was a smoke test. Nothing seem to help so I really started thinking. I thought to myself that from the start, the engine light went on and off for months. I was thinking that something was building up that kept the engine light on. My car only has 60,000 miles on it. Iask myself? could it be the trottle body? It took me an hour from start to finnish to clean the trottle body. when I got done, i hop the the driver seat and closed my eye and said a little prayer and when I started the car!!!!! THE ENGINE LIGHT WENT OFF. MY FRIENDS, IT YOU HAVE A CODE P1101, CLEAN YOUR TROTTLE BODY...I HOPE THIS HELPS
