P0368 - CAMSHAFT POSITION SENSOR "B" CIRCUIT HIGH BANK 1

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.

• Check Engine lamp illuminated.
• Difficulty accelerating.
• General loss of engine performance.
• Increased fuel consumption.
• Engine detonation during deceleration.

The reasons for setting the P0368 OBD2 diagnostic code are:

• The Camshaft Position Sensor "B" circuit may be shorted.
• The CMP Sensor connector could be corroded or have fluid debris in the vicinity.
• Possibly the CMP Sensor "B" is in bad condition.

To troubleshoot the DTC P0368 OBDII code you must do the following:

• It is recommended to start with the verification of the Technical Service Bulletins (TSB). These have useful information for diagnosis.
• Check all wires and connectors that are related to the Camshaft Position Sensor circuit. Repair or replace any burned, frayed or corroded wires. Then with a scanner, clear the code.
• If the code returns, disconnect the CMP Sensor wiring, and with a digital voltmeter test the 5-volt power supply circuit to the sensor. Consult a wiring diagram for the corresponding values. If the actual voltage does not match the specified voltage, repair the wiring from the PCM to the sensor.
• With the DVOM check the Camshaft Position Sensor for proper signal and ground. You should make the appropriate repairs.
