Mass Air Flow Sensor
Mass
air flow sensors are tasked with measuring the amount of air entering
the engine via the intake. This mass air flow sensor is known as a hot
film sensor which will suffer performance deterioration over time. The
sensor is designed to be self cleaning. A faulty or non functioning mass
air flow sensor will cause a check engine light and in some cases cause
a limp mode. The best way to diagnose a faulty mass air flow sensor is
to disconnect it and see if engine idle or performance improves.
Mass Air Flow Sensor Failure Symptoms
Check engine light illumniated with OBD codes related to MAF sensor faults
Engine has rough idle and/or stalls
Short term fuel trim is rich at idle or lean under load
Constantly runs rich or lean
