Bad Mass Air Flow Sensor: When To Replace A Failed MAF

This is when having a bad Mass Air Flow sensor (MAF) becomes a problem. Check My Flow . A MAF sensor is usually placed in-line immediately after the air filter, and takes a reading of how much air is entering the engine. It takes account of the air flow and converts it to an electrical signal sent to the ECU. The ECU sees this reading and adjusts the fuel volume that passes through the ...

P0102 Code: Mass Air Flow (MAF) Circuit Low - In The ...

· Diagnostic trouble code (DTC) P0102 stands for “Mass Air Flow (MAF) Circuit Low.”. The code is set when the powertrain control module (PCM)—your car’s primary computer—perceives a problem with the mass airflow (MAF) sensor’s performance. A faulty MAF sensor can damage other parts of your vehicle, such as the catalytic converter.

Five Signs a Mass Air Flow Sensor is Bad -

· A Mass Air Flow Sensor (commonly referred to as the MAF sensor) ensures the vehicle’s fuel delivery system works efficiently. It’s an electric component that reports how much air is able to enter the car’s engine. This data is then used by the Electronic Controller Unit (ECU) to work out how much fuel is needed. To correctly run an engine requires parts of air for each measure of fuel.
