Could you please tell me which wire is doing what in the cam sensor circuit? I have a red/white, black and brown/white wire. Need to see if I have an open in one of the wires because I have a code P0341.I have replaced the sensor but it did not help. Thank you very much, Fredrik

Red/White = twelve volt ref. Black = low ref (ground). Brown/white = square wave signal (becomes a black wire after the connector). This guide can help you test the wiring with the engine wiring diagrams below.
