Thread: HOW TO: Reground Your MAF (mass air flow sensor)

Pics aren't loading for me and I'm looking to do this to my P10. Anyone got the pics handy?

Sorry about that.. Please check the 1st post again for the link.

Also note, Reground this to the top of the intake manifold stated and pictured in this thread by Vadim in post 23. Not in front of the battery. I am going to have to update those pictures.

On highports, just find where the ECU grounds are, there should be two wires with green on them. They should be in the Intake Manifold area...

You are out of here

so it's the center wire or white wire on a b13?

can someone tell me if i reground my maf and i'm getting 9mV (i didn't test before), does it mean that i have a bad maf?

If you are getting 9mv, try using a larger diameter wire (I used 14gauge) and grounding it on the other intake mani (IM) grounding screw. Make sure your IM connections are clean. Use a copper/gold ring connector at the IM end and solder the other end to your MAF wire. Retest when connections are completed and before the final tape up.

To validate the operating condition of your MAF, do the following:
- Peel back the rubber on the connector. Leave MAS plugged in.
- Turn Ignition switch "ON"
- Start engine and warm to operating temp.
- Check voltage between terminal A (right-most wire) and ground (intake mani).
. . . Plug Position = { * * * X }
. = Ignition switch on (with Engine stopped) - Less the 1.0V
. = Idling Warm Engine - 1.3 - 1.8V

If NG, Check the hot film strip for damage or dust. Try cleaning it with CRC Mass Sensor Cleaner
(follow the directions listed on the can IN DETAIL ! ! Dont just spray it on the film as you will probably cause unrecoverable damage).

were can we get that mass sensor clearner from?

Any parts store

Heres the CRC cleaner.. Call around to your local parts stores for it.
