How to: MAF Sensor Test Procedure

[Kevinh71047]

Light Blue/Red stripe wire should be the MAF sensor signal
Tan/Light Blue stripe wire should be the MAF sensor return
Measure the voltage between the above two wires while the MAF sensor is connected and the engine is running at idle speed. Then increase the engine speed and see how the voltage changes. The OHV V6 MAF sensor is not the same as my SOHC V6 MAF sensor so the values will be different.

On the wires you said they spiked up and down when i gave it gas

That is not an informative response. What was the voltage at idle? Did it increase smoothly as the throttle was slowly opened? What was the voltage at 1500 rpm, 2000 rpm, 2500 rpm?

No it idled around 1000 but it went up and down i. Guess its some electrical issues
