What does unplugging MAF sensor do?

If you disconnect the mass airflow sensor, then the car should keep running and still be able to start normally. This means that if your mass airflow sensor dies completely, then your car will stay running and surprisingly the car might run better without the mass airflow sensor.

Where is the mass air flow sensor located?

Updated: February 18, 2020 A Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine.

How does the air mass sensor work in a diesel engine?

The air mass sensor precisely measures the air mass that flows into the engine (“mass air flow”). The signal from the air mass sensor is used to calculate the injected fuel quantity. In diesel engines, it also controls the exhaust gas recirculation. It is an important component in air supply and helps reduce exhaust gas.

Where can I find the trouble code on my air flow sensor?

When the air flow sensor signal varies from the expected range, the PCM records a fault and stores the corresponding trouble code, illuminating the Check Engine light on the dash. This trouble code can be retrieved with a scan tool. The following trouble codes are usually associated with a mass air flow sensor:

What can cause a MAF sensor to fail?

The sensor element could get contaminated or damaged. Sometimes, an improperly-installed or ripped air filter can cause the MAF sensor to fail sooner. Over-soaking a washable air filter with oil can also cause troubles with the air flow sensor.
