Technical Description
The Camshaft Position Sensor B Circuit Malfunction (Bank 2) refers to a generic powertrain code that applies to OBD-II equipped vehicles. The specific repair steps may vary depending on the make and model of the vehicle.
The P0390 trouble code indicates a problem in the camshaft position sensor circuit of bank 2. This means that the issue could be in the sensor itself, the wiring, or the PCM. Simply replacing the CPS (camshaft position sensor) may not necessarily fix the problem.
Note: The camshaft sensor “B” is typically located on the exhaust camshaft. While this code is similar to P0345, it is important to consult a vehicle-specific repair manual to identify the correct sensor for your vehicle/engine.
