What does it mean?
This diagnostic code (DTC) is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary slightly by model.
It indicates that a problem has been detected in the Bank 2 camshaft position sensor circuit.
Since it says circuit, it means the problem could be 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 may include:
Hard starting or no start
Rough running / misfires
Loss of engine power
Causes
A P0345 code could mean that one or more of the following events have occurred:
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 is an open circuit
the crankshaft position sensor may have failed
Possible Solutions
With a P0345 OBD-II trouble code, diagnosis can sometimes be difficult. Here are some tips to try:
Visually inspect all wiring and connectors in the circuit
Check the continuity of the circuit wiring
Check the operation (voltage) of the camshaft position sensor
Replace the camshaft position sensor if necessary
Also check the crankshaft position circuit
Replace the circuit wiring and/or connectors as needed
Diagnose/replace the PCM as needed
