hi everyone i have got this omega in with mil on and the fault code which will clear but will come back after the engine starts and the rev's are limited to 4500 i have scoped it and and get a similar waveform with ignition on and engine running this is the sensor with the fork and one bolt inside the cam belt cover i have replaced it with genuine but it's still the same it's got 3 wires 1 is the earth the middle is the signal but i don't know what the third wire should have it shows nothing with ignition on or with engine running. any ideas anyone?
