I had what was a rather numerous amount of low voltage codes, I then replaced ecm and the harnesses, codes remained.

Pedal sensor voltage too low
Cam sensor too low
Fuel pressure sensor too low
And map sensor too low

I tested the voltage at the pedal sensor and it tested with in spec according to prodemand manuals 1 to 5 5v, 2 to 3 5v.

I then plugged pedal in, tested the cam position sensor, 1.5v 1 to 3... way out of spec..

I unplugged the pedal, and the cam sensor went to 5v

Plugged pedal back in, immediate voltage drop..

As I mentioned before the harness voltages to the pedal sensor 2 are good.

I believe with these tests the pedal is faulty, any opinions?
