View Full Version : SR MAF Re-Grounding

Hey again. I couldn't find a descriptive nor pic heavy thread. If I wanted to reground my redtop MAF would I literally just cut the middle (ground) wire and ground it up to the chassis like any other one? Thanks.

If you remove the ground for the mafs, the ecu should throw a code. The ecu has a separate ground pin for the mafs, a reference. If you were to ground the mafs to the chassis or common ground the mafs will still function but you'll get a code from a working ecu.

So why do you want to ground the mafs to the chassis?
If you have a bad pin in the ecu, it can most likely be repaired.
So I'm not telling don't do it, it's your car? But i would look for an alternative or find out why i needed to reground the mafs.

If I'm not mistaken the middle wire is the SIGNAL wire to ECU, not a ground. This is a shielded wire.

Idk I was just reading on what some people do for mpg and performance and from what I understand this give a noticeable difference. I have seen it many places but I think Ill just say screw it lol. Why take a chance at screwing it up

If it doesn't work you can just solder it back hah
