I'm starting to wonder if I have a wiring problem, not broken, just not in the right place.
I received yet another MAP sensor today and this one does the same as the others. Now this CAN NOT be possible.
With the K-series T-MAP sensor I am getting a reading that changes with vacuum, I wired this one up myself, I did not rely on ready made plugs and wiring looms.
Could the wiring in my car be wrong ? could they be crossed ? could the 5 volts that should be powering the MAP sensor be going to the signal pin ???
Is there anyone wire a very early MPI that has the early ECU that can take a photo of the MAP plug and wires ?
And someone with a late MPI who could do the same ?
Mine is a later one but it has an early ECU ***191 and it should have the ***192 ECU ! (i got the car in bits)
Someone did mention that the difference between these 2 ECUs has something to do with the MAP sensors. So I'm wondering if there is a wiring difference between the 2.
Or if anyone has any ideas about what the F is going on. HELP ME PLEASE.
Pete.
