What causes low voltage on a mass air flow sensor?

The MAF Sensor has low voltage output problems which may have several causes. The source of the problem is the sensor range voltage is lower than normal or required by the ECU to function properly. ... The MAF sensor can also be dirty or partially plugged with carbon causing a low reading.

Can a mass air flow sensor cause transmission problems?

The Mass Airflow Sensor measures airflow into the engine intake assembly and is used to determine engine load. If it fails it can cause automatic transmission problems such as late harsh shifts, early soft shifts, or can result in no shifting at all.

Can a dirty air filter cause P0102?

The primary reason for a P0102 code is restricted airflow.

This situation is caused by a dirty or clogged air filter. Upon stepping on the gas, the engine needs to ingest a lot of air.

What does mass air flow circuit low mean?

Diagnostic trouble code (DTC) P0102 isn't in every vehicle's code library, but whenever it appears it means “Mass Air Flow (MAF) Circuit Low.” The code is set when the ECM/PCM perceives a problem with the mass airflow (MAF) sensor's performance. The MAF sensor is mounted between the air filter and the throttle body.

What should MAF sensor read?

MASS AIRFLOW SENSOR OUTPUT

Output at idle is usually 0.4 to 0.8 volts increasing up to 4.5 to 5.0 volts at wide open throttle.

Can you drive with a bad mass air flow sensor?

Yes, you can drive within such a sensor situation, but you can ride a car or truck for a specific duration. ... The bad mass airflow sensor problems can cause different drivability issues. The drivers can easily experience the lack of power in the engine, no-engine start, poor acceleration, and more during the drive.

What happens when mass air flow sensor fails?

A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. This causes the engine computer to miscalculate the amount of injected fuel. ... As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration.

Where is the mass air flow sensor?

The mass air flow sensor (MAF) is a key component of the electronic fuel injection system in a car. It is located between the air filter and the engine's intake manifold.
