Voltage to the pcm or the power voltage going in to the sensor

I would say you have a wire going to the map sensor thats close the map sensor that is bad. Probably the copper wire is broken inside the insulation. To me thats the only thing that makes sense at this point.

What do you mean by close the map sensor

I missed a word close to the map sensor. Meaning when you unplug or plug in the map sensor connector you disturb the bad wire.

I understand now. One I mit have a bad wire or two I have a bad plug. So what you are saying is test the wires when I move them around and test that plug to see it one breaks the connection

Heres what I would do put the key in the run position engine off watch the map sensor volts while moving the wired connector etc around.

Ok I have checked the connection at the sensor and moved around the wires and everything seems tobe fine with the connection and I also checked the voits the power wire was 5 volts and the signal wire was 4.5 volts but im wondering about the ground wire that goes to the sensor

Are these readings with the map sensor plugged in?
