Hello, I have a CEL for MAF sensor stating check ground wire. Ive googled videos and attempted to find the wire diagram elsewhere to no luck. Where is the ground for the MAF sensor located.

What is the code? There'* no code that says check the ground wire.
Is the car running good?

It’* located underneath the ignition module/coils bracket. Hope this helps.

what is your code number, because you are lying or you googled the number and someone said the ground wire, but without the code number you could be chasing a ghost since it may not be the issue. What is the code, and what engine do you have, a supercharged one or a Naturally aspirated one(the NA one has a black plastic intake while supercharged is a metal one)
