MAP P0107
Ok I have been messing with this for 2 days. I have a Power 5.02v form the ECU then Power out and Ground. (3 wire) When I turn on The key the computer reads low input voltage. ANd sets off a SES light.

I tried small resistors 10ohm and 20ohm to drain off volts to ground on both wires and still get the Po107.

I tried the Map kit got the same results.

Anythoughts?

P0107 = the ECM saw MAP voltage below 0.1 volts for the specified crankshaft revolutions. You are taking that voltage too low.

RE: MAP P0107
Ok here is what I did. On in Signal wire not the 5v input wire.

I Put a 20K potentiometer inbetween the signal and ground. This gave me the 4.82v need for the start up. then once it is running I trimmed off some mv. Seems to work ok. but once you hit a hill you have to trimm back. For slow 40mph driving it is ok.

I am going to use a different potentiometer for this. I need a knob on it. Right now I have to use a small screwdriver.
