I'm having an issue with a p0107 map sensor low voltage. I've cleaned the sensor, and it is showing 5v on the supply side, and 4v at idle on the signal. It shows dropping voltage when throttle is applied. Chased the signal wire to the plug at the PCM. Showing voltage the same at the plug as the sensor. I'm kind of at a loss. Any suggestions?

 

This was tested at the MAP, above the thermostat housing. today I tested the TMAP, on the intake manifold and found it to be without voltage on the signal wire, despite having 5v on the supply side. i was under the apparently mistaken impression that the TMAP was covered by other codes. New TRMAP sensor will be here tomorrow and I will update if the issue is solved.

 

Hi I am interested if you solved the problem by exchanging the TMAP sensor?
Thanks
