Saturn S-Series Forum : “MAP Sensor -5 volts”
MAP Sensor -5 volts
I have a 105 code (MAP Sensor). I replaced and cleared. Code came back. The voltage on the sensor is reading -5. All other sensors are +5. Smoke tested and no leaks found.
It's possible you got a bad MAP sensor when you replaced it. Can you get an actual reading of what pressure the MAP sensor is recording? If there is a small crack in the line to it the MAP will read atmospheric pressure instead of actual manifold pressure and throw a code. How are the wires to the MAP sensor, are they intact without any cracks or breaks in the insulation?
