Ford Expedition 2005 Cam Sensor Wiring Diagram
P0345 Camshaft Position Sensor Circuit Malfunction Bank 2
Technical Description
Camshaft Position Sensor A Circuit Malfunction (Bank 2)
What does that mean?
This diagnostic trouble 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 be slightly different depending on the model.
This indicates that a problem was detected in the camshaft position sensor circuit of bank 2.
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 P0345 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 P0345 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
