The most common causes behind the error code P0340 of your S-MAX

  • Faulty PCM (Power Control Module)

What is the error code OBD-II P0340 of your S-MAX?

The error code P0340 signals that there is a problem with the circuit of the camshaft position sensor. This sensor determines the rotational speed and the camshaft position, and then it sends this information to the PCM. With this information, the PCM synchronizes the timing of the fuel injection with the timing of the ignition system (the spark). When the signal between the sensor and the PCM is interrupted, this synchronization fails and the engine may behave erratically. You will know that there is a problem because the “check engine” light will come on and it will show the code P0340 when you scan your car.
