Why is my p0340 camshaft position sensor not working?
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. With a P0340 Fiat OBD-II trouble code, diagnosis can be tricky at times.
What does the OBD-2 diagnostic code p0340 mean?
The OBD-II diagnostic trouble code P0340 indicates a “Camshaft Position Sensor “A” Circuit Malfunction.” It covers the entire circuit attached to the aforementioned sensor, such as the electric wiring and the powertrain control module (PCM).
What’s the difference between p0335 and p0340?
A similar code is P0335, Crankshaft Position Sensor “A” Circuit Malfunction. Like P0340, P0335 also warns about a problem in a sensor’s electric circuit. The difference is that P0335 covers the crankshaft that converts engine power into forward motion, while P0340 involves the camshaft that controls the intake and exhaust valves.
What causes a p0340 to set on a Mustang GT?
Ford Trucks / Mustang GT – An alternator phase problem, such as a blown diode or open coil, may cause so much electrical interference that the CMP signal gets distorted, causing a P0340 / P0345 DTC to set, among others, in spite of there being no actual problem with the CMP sensor or wiring.
How to diagnose p0340 OBD-II trouble code?
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
What does a code p0340 mean on a PCM?
A code P0340 could mean one or more of the following has happened: 1 a wire or connector in the circuit could be grounded/shorted/broken 2 the camshaft position sensor may have failed 3 the PCM may have failed 4 there exists an open circuit 5 the crankshaft position sensor may have failed
What to do if your camshaft position sensor says p0340?
Visually inspect the camshaft position sensor connector in search of corroded or broken connectors. Make any other repairs (if other codes are present) to make sure that other codes are not sources of the trouble code P0340. Check your camshaft position sensor’s voltage, ground, and signal readings with a multimeter.
