Low MAF signal. Hooked up my shops snapon scanner and the MAF is reading 0 for every input. Pretty much the MAF is not working, but the car still drives, the idle is kinda jumpy also.

Anyone know the resistance, voltage, etc for the MAF.

It's a 2000 v6 auto

 

Check to make sure the MAF sensor is getting +12V power. There should be a pink wire in the connector that supplies the 12V power to the sensor. If you have 12V and a good ground, its probably a faulty sensor.

The output signal from the MAF sensor is a variable AC frequency. The PCM has a table that converts the frequency to mass-air flow in grams/second. The code sets when the frequency drops below 1200HZ.

 

I'm getting 0HZ and no other info. Gonna do some electrical trouble shoot when i get to work.

Thanks.

 

Anyone got a part number for a MAF unit on the 3.8 v6?

 

Pink wire gets 13.x volts. MAF is confimed dead.

 

Make sure the pins on the harness connector aren't damaged.
