See i need to Know the Diagram of those Three Wires On the Crank Position Sensor ,
Which for What .
This Is the Plug .
What's the Wires Reffer to .
Like GND , Positive 12V & Signal .
Which one Is Signal and Which one is Gnd and Which on is 12V ?
Crank Position Sensor Diagram/Wiring ???

Its a VR sensor with an earthed shield.
Wish I had checked the one I had apart last night now.
IIRC the centre pin is the earthed shield, and one of the outer two is the black or yellow to the sensor.
There is only actually 2 wires to the sensor.

Two of the pins should have a resistance of around 550 ohms between them, and infinite resistance to the third pin.
There is no voltage supplied to the sensor - it is a generator in itself.

As above, and IIRC the ecu is looking for the change in resistance/voltage as the trigger wheel passes rather than any set value.

Classic this three pin designs, catches out all the tuners!
