    Cam install...CEL's

    Just installed a blower cam on a 2010 camaro with the tvs2300. Popped a P0340. This is the cam position sensor circuit if i remember correctly. Where is this located at and and any thoughts on why it is going off. If i find where its located at we can make sure it was hooked up properly and then continue on figuring out why its going off.

    P0340 OBD-II Trouble Code

    Technical Description
    Camshaft Position</font> 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.


    Symptoms
    Symptoms can include:


    •Hard starting or no start
    •Rough running / misfiring
    •Loss of engine power

    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

    apparently the issue is with the cam gear itself. i need a stock ls2 three bolt cam gear not an ls1 cam gear.

    that's exactly what it is. cam gear has the "windows" for the sensor built into it, and your new gear likely does not. gear is less than $25 tho, just sucks to hafta go back in to change it....

    But can you keep the VVT sensor with non VVT cover (shorter) or needs to put a non VVT sensor too?

    Cam sensor needs to be changed to a non-VVT sensor.
