P0340 OBD-II Trouble Code
Technical DescriptionCamshaft 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.

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
