What does a bad air flow sensor cause?
A bad MAF sensor can cause your vehicle to experience poor drivability issues such as engine stalling, jerking or hesitation during acceleration. This could happen while speeding up on the highway on-ramp or cruising down a city street. These issues can create dangerous situations causing accidents and injury.
What causes the mass airflow ( MAF ) sensor to have low voltage?
P0102 is the general code for a problem with the Mass Airflow (MAF) Sensor having a low voltage output to the Engine Control Unit (ECU). What causes the P0102 code? The MAF Sensor has low voltage output problems which may have several causes.
What is the trouble code for mass airflow?
P0102 is a diagnostic trouble code (DTC) for “Mass Airflow (MAF) Circuit Low Voltage Input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
What is the trouble code for a MAF sensor?
Note: Some MAF sensors also incorporate an air temperature sensor, which is another value used by the PCM for optimal engine operation. Closely related MAF circuit trouble codes include P0100, P0101, P0103, and P0104. Photo of a MAF sensor: What are some possible symptoms? Symptoms of a P0102 code may include:

What is the error code for mass air flow?
Error code P0102 means the mass air flow sensor had lower than expected voltage input. In vehicles with electric fuel injection systems, the mass airflow (MAF) sensor determines the flow-rate of air going into the engine through the intake valve.
