MAF Problems

[Wolf240SX]

Ok Here is the situation. I am not getting a signal from my maf. I upgraded to a Cobra MAF. I checked the MAf and it is working fine. I checked the power and it is getting power I checked the power ground an it is grounded I checked the isgnal ground and it is grounded. I checked the continuity of the signal wire and it is ok. It was working fine then I was tiinkering under the hood so I disconnected the power ground to move it out of the way. When I hooked it back up the MAF would not work. Does anyone ahve any solutions or encounterd this problem before? Please help. I want to drive my car again.

yes car runs but is in safe mode IE will not rev beyond 2500 rpms and the code I sm getting from the ecu is 12 which is the MAF code

You've checked the new ground you just installed?

Sounds to me like since it was working and the only thing you did was change a ground, then it's either a bad ground, or you toasted the MAF. Don't know if that's possible with the engine off, but I always unhook the harness to be safe.

ok solved the problem. What happened is when I was tinkering under the hood. I accidently pinched the signal wire and grounded it to the chassis. I took the pinched wire off and replaced it with a new sectionof wire. The car runs as good as new now.
