Gm Mass Air Flow Sensor Wiring Diagram
46+ Gm Mass Air Flow Sensor Wiring Diagram PNG. I also show you how you can figure out the wires without a wiring diagram. No scan tool is required or any other expensive testing equipment.
The mass air flow (maf) sensor measures the flowrate of air through the air intake before reaching the engine.
An engine with a bad maf sensor may with the bosch hot wire sensors, sensor voltage output can be read directly with a digital voltmeter gm says that repeated instances of mass air flow (maf) sensor failure on some of their vehicles. How to test a maf sensor using a basic multimeter without having to look up a wiring diagram. Hot wire type the primary components of the maf sensor are a thermistor, a platinum hot wire, and an electronic control circuit. Mass airflow sensor diagnostic fault codes.
