P0393

DTC P0393, sometimes indicated as P039300 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the ignition system causing camshaft position sensor "b" circuit high (bank 2).

This code is set when the Camshaft Position Sensor "B" (CMP Sensor 2) signal is above the manufacturer's preset limit. This code is most commonly caused by a bad Camshaft Position Sensor "B" (CMP Sensor 2), but may also be caused by a bad Camshaft Position Sensor "A" (CMP Sensor 1), wiring problem, or ECM.
If this code is present, inspect the Camshaft Position Sensor "B" (CMP Sensor 2) and the wiring. If the sensor is bad, replace it. If the wiring is bad, repair it. If the ECM is bad, replace it.
