Symptoms of a Bad Mass Air flow Sensor A bad sensor displays a temperature of the air more than the coolant level; this causes the engine control unit to reduce the fuel flow, followed by lean operation and reduction of the fuel economy. make sure your mass air flow sensor is clean b Auto repair shops hate this video. Spray 10 to 15 spurts of the (MAF) mass air flow sensor cleaner onto the wire or plate. Mass Air Flow Sensor Based on research, it appears that these codes could be the result of the MAF sensor gone bad.

The Mass Air Flow sensor is used to measure the amount of air entering the engine. Mass Air Flow Sensor Diagram The sensor pictured on the right, converts air flowing past a heat sensing element into an electrical signal. The mass airflow sensor (MAF) measures the amount of air entering the engine. This information is then sent to the vehicle's engine management computer, which injects the proper amount of gasoline into the cylinders. The dealer replaced the mass air-flow sensor approximately two years ago and recharged the ecm. 00.
