Truck is back from transmission repair... now... DTC
P0340 -
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
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
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
P0054 -
P0054 HO2S Heater Resistance (Bank 1, Sensor 2)
Sounds like you might need a CPS and a O2 sensor...
