ok. Looked everywhere and cant find an answer. Can ANYONE tell me what the volts are for the MDP (MAP) sensor?
I found a test of a generic one (not from any specific vehicle) from youtube, and all the #'s were correct except one.
_______________
l__0____0___0___l <--- Wires
l__1____2___3___l <--- Wire #'s
First wire (on the left (if still connected to MAP sensor)) = Reference Wire
Second wire = Signal Wire
Third wire = Ground wire
I was told that the reference wire should be about 5v. / the Signal wire between .85v and 1.3v / and the ground at 12v
Well I'm getting the 5v. from the Reference wire
I'm also getting the 12v. from the ground.
BUT i'm only getting .06v from the Signal wire.
Can anyone tell me if this information I found is accurate to these cars???
Ecu is shot!
