Cam sensor question
Car will not start. Found something odd to me today. I was probing the cam sensor wire harness and from what I understand is the RED is 12v supply, PIK/BLK is ground, and BRN/WHT is sig. Here is what happens....
Power on to the PCM
Test light grounded and stick RED, 12v and it triggers the fuel pump relay...?
Test light on power(hot) and stick PNK/BLK and get ground...good
Test light on power(hot) and stick BRN/WHT and get nothing.....?
Why does the PCM get signal from the red 12v supply and nothing from the BRN/WHT??
