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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eMass Air Flow Sensor\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMass air flow sensors are tasked with measuring the amount of air entering the engine via the intake.
