The air filter does it’s best to clear the air but over time the MAF will get dirty, it’s a matter of “when” rather than “if”. Being part of the intake, the sensor wire/ plate (part of the sensor unit) is exposed to all the dirt and grime in the air, sucked into the car’s intake. Mass air flow sensors are part of a vehicles intake and take readings of the amount of air coming into the engine, allowing the vehicles computer to understand the amount fuel required, allowing the engine to run efficiently. Fuel economy can also suffer as the engine struggles to retain its optimum running conditions, thanks to faulty sensor readings coming back from the MAF. The Best MAF Sensor Cleaners on the Marketįixing your car with a cleaning product? Poor starting, rough idling and poor performance could all be signs that a vehicles mass air flow sensor (MAF) is getting covered in road grime and dirt.

If there is anything that you would like to add, please feel free to leave a comment below. Replacing a bad MAF sensor can make your Cruze feel like a new vehicle. About a dozen small bursts will be all that you need.

Clean the Sensor– Now that you’ve removed your Cruze’s MAF sensor, it’s time to clean it.

Simple hand tools will be all that you need to complete the job.

Remove the Sensor- Take care not to damage the wiring harness or the connector pins that receive the harness in the MAF.

Locate the MAF Sensor– It’ll be in between the air filter and the throttle body.

It sure beats the heck out of having to buy a new sensor. It’s really cheap and available at any parts store. This is a bad idea, it can ruin the sensor. Some folks recommend using alcohol because it’s usually on hand, and can clean the sensor. Often, the mass airflow sensor really only needs cleaning when they go bad.

Here’s a fantastic video on how to diagnose a bad MAF sensor using a multimeter from Ratchets and Wrenches on YouTube. There are other codes related to the mass air flow sensor as well, but these are the most common ones.

Chevy Cruze P0101 Diagnosis: MAF Sensor.

The two most common trouble codes in relation to the MAF sensor are: This is great because it helps you narrow down the problem. If the MAF sensor has gone bad, it’ll trigger the check engine light and provide an OBDII trouble code. Here a couple of common MAF sensor styles

Decreased Fuel Mileage– Fuel mileage can suffer without the proper air/fuel mixture.

Also, jerking can be caused by bad spark plugs or coil packs. It’s bad for your motor mounts when this happens.

Jerking– As you go down the road, you’ll feel your Cruze really jerk and hesitate as the engine speed changes erratically.

And when it does, it doesn’t usually run very well.

Hard to Start– Without knowing the proper amount of air entering into the intake, it can be really difficult for the engine to start.

The exhaust color usually doesn’t change. A lean condition is when there is too much air relative to fuel in the air fuel mixture. The exhaust color is usually darker when running rich. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture.

Idle Issues– Your Cruze may run rich or lean when idling, or it may also idle erratically.

Here are the most common symptoms of a bad or failing MAF sensor: When the mass airflow sensor has gone bad, you’ll definitely feel it. And, most of the time they are right by the air box and easy to replace.įaulty Mass Airflow Sensor Symptoms: Chevy Cruze If you do determine that you need a new mass airflow sensor, they aren’t too expensive. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber. It passes this information onto your Cruze’s ECU. A bad mass airflow sensor can leave your Chevy Cruze’s engine running rough, or even inoperable.Ī MAF sensor measures the density of the air entering the intake manifold. The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors.
