Angry Help with a P0651 5volt #2 2004 redline

So I have the code P0651 5volt #2 I am wondering if anyone else has had to address this issue and if so what was their fix. Also, what should I check with a multimeter to determine what has the less than 5volts or a short going to it? Right now the vehicle is in limp mode it started off as the throttle body then the gas peddle. I replaced both of them so those codes are gone I do have codes for up & downstream 02 sensors not sure if that would cause it I did have a code for an ac sensor. I just bought the car so I am not sure what has been done to it I did notice it had a whole lot of zzp parts it does have a header and a zzp exhaust system any help would be appreciated.

Never mind the bolt came lose for the hold down bracket on the map sensor and was causing the 5volt problem.
