01 Volvo v70 xc Cam/crank Sensor
Decided to step back a little and check the least cost first between the cam/crank sensors and the ECM, Crank sensor is good, but the Cam is a little funky. As I read, the supply and signal voltage should be 5V. For Supply voltage I checked the power coming from the female side and it is delivering its 5V. Plugged in the Camshaft sensor, turned the car on and back-probed from the Camshaft side for the supply voltage, got 5V. Now as I understand, electricity flows from positive>load>negative, which means from supply through trigger (or Signal). Unplugged, and car on, i get the reading of 5V from my signal wire from the Female side, but when I plug the Camshaft sensor in, and back-probe from the camshaft, I get 87.8mv.
So my 2 questions are this: 1- Is the signal voltage suppose to come from the female side or the Camshaft side? 2- Since the reading im getting is 87.8 mv, can i safely assume that the camshaft is bad?
