    P0340?????? Ok so my car has thrown this code every so often. I have a Cobb AP v1 and have just cleared it myself. The last time I was at a dealership for an oil change I asked about the code and no one there could give me an answer. Does anybody Know what this is? And if it is a problem, how to fix it?

    Camshaft Position Sensor Circuit Malfunction
    What does that mean?

    This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

    Causes

    A code P0340 could mean one or more of the following has happened:

    * a wire or connector in the circuit could be grounded/shorted/broken
    * the camshaft position sensor may have failed
    * the PCM may have failed
    * there exists an open circuit
    * the crankshaft
    position sensor may have failed

    Possible Solutions

    With a P0340 OBD-II trouble code
    , diagnosis can be tricky at times. Here are some things to try:

    * Visually inspect all the wiring and connectors in the circuit
    * Check for continuity in the circuit wiring
    * Check the operation (voltage) of the camshaft position sensor
    * Replace the camshaft position sensor as required
    * Check the crankshaft position circuit as well
    * Replace circuit wiring and/or connectors as required
    * Diagnose/replace the PCM as required

    ^^^^^ Ok. You are assuming I am mechanically inclined; which I am not. I would need to go to someone to resolve this. Who could help?

    Thanks. I didn't notice that thread. I did do a search through back threads but specifically for the code and came up empty. Again thanks.
