Common causes:

• Faulty camshaft position sensor
• Open or short in the wiring harness
• Poor electrical connection at the camshaft position sensor
• Engine timing issues
• ECU/PCM software needs to be updated

 

Common Misdiagnosis

OBD2 Code: P0368

Description: Camshaft Position Sensor B Circuit High Bank 1

Common Misdiagnosis: Replacing the camshaft position sensor without checking for wiring issues or problems with the timing chain/belt.

 

Common Diagnostic Steps

OBD2 Code: P0368

Description: Camshaft Position Sensor B Circuit High Bank 1

• Check the camshaft position sensor wiring and connectors for damage or corrosion.
• Inspect the camshaft position sensor itself for any signs of physical damage.
• Use a multimeter to test the voltage and ground signals at the camshaft position sensor connector.
• Verify that there is proper continuity in the wiring between the camshaft position sensor and the engine control module (ECM).
• Check for any related trouble codes that might indicate an issue with other components, such as crankshaft position sensors or timing chain/belt problems.
• If equipped, inspect and test the variable valve timing (VVT) solenoid for proper operation.
• Clear all codes after repairs are made and perform a road test to ensure the issue has been resolved.
