Heya, first post
I'm trying to figure out a code 22 on my 93.
Ive read some great advice here, and here's what I know:
Replacing the MAP did not cure the code. I used a new Motorcraft MAP.
The MAP is not incorrectly connected to a vacume hose
When the harness is disconnected from the MAP, 5volts are present at both the black wire and the green signal wire (I've read some conflicting info about the proper voltage of the green wire as 5v or 0v).
The resistance between the black wire and the same wire at the TPS and EGR is about 1ohm
However the resistance between the black wire and the neg. battery cable is quite high. This may be the problem, but Im not sure where to dive in to fix it.
Any advice?
