Asked on September 3, 2011

Is there an at home test i can do to check my MAF sensor to see if it is good?

2008 Ford Fusion, replaced MAF sensor because CEL came on. It stayed on until yesterday when the car began to stall out and hesitate while pressing the accelerator. I ordered an air pump because this is what i am now being told the issue is. I am wondering if the New MAF sensor i put in is bad or not. And if so is there a way around this without the purchase of another?

Could be caused by one of the following below

Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.

Note:If it doesn't apply disregard it and keep testing.
