The CMP (Camshaft position sensor) is an electronic device that detects the position of the camshaft. This information gathered by the sensor is sent to the PCM (Powertrain Control Module) in a voltage signal, to make adjustments to the fuel injection timing.
The P0368 OBDII fault code is a generic code that is set by the PCM when it detects that the CMP Sensor “B” for bank 1 has a high circuit condition. The reason for this code is usually due to electrical problems.
