The P1101 error code is without doubt one of the mostly saved faults in Chevy Cruze fashions and might seem on each generations of this compact automotive. It seems to be extra prevalent on examples with the 1.4-liter turbocharged or 2.0-liter turbodiesel engines, however isn’t unusual in non-turbo gas-powered Cruzes, both.

One in every of these sensors is the Mass Air Move sensor (MAF), which displays the amount of air coming into the engine, and the ECU will illuminate the CEL straight away if it detects that the MAF sensor’s output sign is out of vary or absent. Connecting a scanner to the OBD-II (diagnostic) port whereas this error is current will then current the P1101 and/or P0171 error codes in its reminiscence, probably accompanied by an outline alongside the strains of “Consumption Airflow System Efficiency”.
Moreover, the ECU can even acknowledge a defective MAF sign when the automotive is being pushed and can alert the motive force to any Chevy Cruze Mass Air Move sensor issues which can happen whereas on the transfer. This is applicable to all mannequin years and seems to be prevalent on the gas-only lineup from 2011, 2012, and 2013. It seems on the diesel fashions, which arrived with the 2014 facelift, and remained a typical situation for the 2015 mannequin as nicely. The second-generation automotive, which arrived within the US in 2016 and remained accessible for 2017 and 2018, has completely different digital structure and new engines, and experiences of this drawback within the second-generation mannequin should not frequent.
Chevrolet Cruze P1101 Error Code Signs
Aside from an illuminated CEL, there are a number of different signs of an issue associated to the Chevy Cruze’s Mass Air Move sensor system:
- Tough idle high quality
- Poor efficiency – particularly so on turbocharged fashions, however noticeable on non-turbo engines as nicely
- Hesitation or surging whereas accelerating
- Extreme gasoline consumption
What Ought to I Do if My Chevy Cruze Exhibits the P1101 Code?

Attend to this situation as shortly as attainable, although, and keep away from heavy throttle functions and excessive engine speeds, as a result of the consequences of such driving circumstances mixed with an air mass meter error may lead to unpredictable efficiency, failure of different emission-control programs, and finally, costly engine injury.
How To Repair or Reset the P1101 Error Code on a Chevy Cruze
With regards to a repair for the P1101 error code on a Chevy Cruze, the difficulty could be pretty simple to deal with. There are a selection of attainable causes for a Chevy Cruze P11011 code, nonetheless – here’s a information on how you can cope with it:
- A unclean or clogged air filter can lead to incorrect MAF readings, so first examine the engine air filter and exchange it if there’s seen dust on the filter aspect.
- Engine wiring harness issues can even trigger errors with the air mass meter’s alerts. Test the wiring across the throttle physique (close to the firewall in the back of the engine) and the air mass meter (positioned on the air filter housing) for injury, particularly contemplating the enviro-friendly soy-based insulation used on the wires may be very engaging to rodents. If the injury is minor, you possibly can restore the wiring harness and its insulation your self, however you must seek the advice of an auto electrician concerning the restore if the injury is in depth. Additionally, verify the battery’s cost charge with a multimeter as a result of an insufficient energy provide may additionally set off emission-related errors.
- Contemplate a vacuum leak someplace across the consumption manifold, more than likely from a cracked or perished vacuum line, throttle physique seal, or consumption manifold gasket. If the leak originates from a vacuum hose, you must be capable to exchange it with a recent hose from the auto spares store, but when a gasket causes the issue, it’s possible you’ll need to get skilled assist for the restore.

That is significantly probably on automobiles with aftermarket foam-and-oil air filter parts as a result of these filters repeatedly launch microscopic oil droplets into the airstream. These droplets then acquire and bake onto the hot-film air mass meter’s sensing plate, resulting in incorrect output alerts. As quickly as the brand new MAF is fitted, the ECU will see applicable sign values once more and shortly flip off the CEL by itself.
- The P1101 error code on a Chevrolet Cruze may be displayed alongside different diagnostic error codes, equivalent to P0106, P0299, P0507, and P2096, during which case the MAF sensor or its wiring is more than likely not the reason for the issue.
