P0014 code definition

Camshaft Position “B” - Timing Over-Advanced or System Performance (Bank 1)

What the P0014 code means

P0014 is the OBD-II generic code that the engine control module (ECM) has determined that the bank 1 exhaust camshaft is more advanced than what the ECM has commanded it be. This over-advanced condition could be during advancing or retarding of the camshaft timing.

What causes the P0014 code?

  • The exhaust camshaft has advanced too much when the ECM has commanded the camshaft to retard to a lower timing level.

  • The oil viscosity is excessive causing the passages to become clogged, causing oil flow to and from the camshaft phasers to be restrictive.

  • The camshaft phaser is seized in the advanced position.

  • The oil control solenoid to the bank 1 camshaft may be shorted in the open position.

What are the symptoms of the P0014 code?

  • The Check Engine Light comes on indicating a problem.

  • The engine may start hard if the camshaft is stuck too far advanced.

  • Fuel mileage will be reduced due to the camshafts not being in their optimal positions for good fuel mileage.

  • Engine may run rough or stall depending on camshaft position

  • The engine emissions will cause the vehicle to fail emission tests.

Note: The symptoms may change depending on the camshaft timing positions when the camshaft phaser stopped moving the timing.

How does a mechanic diagnose the P0014 code?

  • Performs a visual inspection of the connector, wiring, or valve for any problems with the OCV for the bank 1 exhaust camshaft

  • Checks the engine oil level and condition of the oil to see if it is full and if it is the correct viscosity

  • Scans and documents the engine codes and views the freeze frame data to see when the code was set

  • Clears all codes then runs the engine to see if the P0014 code returns and the failure is still present.

  • Monitors timing data while disconnecting the OCV to the exhaust camshaft to see if the timing changes. A change would indicate that the valve is working and the problem is in the wiring or ECM

  • Performs a manufacturer's specific pinpoint tests for the P0014 code and repair as needed

Note: Follow the manufacturer's recommended pinpoint test to narrow down the problem, since each engine may be tested differently and possible engine internal damage may be done if tests are not performed in accordance with a correct procedure.

Common mistakes when diagnosing the P0014 code?

Follow these simple guidelines to prevent mistakes:

  • Do a visual check for common problems to see if all electrical connectors are secured and free of corrosion.

  • Check the engine oil to see if it is full, clean, and of the correct viscosity.

  • Test to verify the code keeps coming back before any further tests are done.

  • Manufacturer test procedures should be followed step-by-step to prevent a misdiagnosis and replacing of good components.

  • Do not replace any sensors or components unless tests indicate a problem.

How serious is the P0014 code?

  • The engine may run erratic and stall or have a hard starting problem.

  • Fuel consumption may increase causing carbon to build up on the engine valves and pistons.

  • Driving the vehicle for a prolonged time with the camshaft out of time can cause valves to contact the piston if the timing chain has jumped the gear teeth.

What repairs can fix the P0014 code?

  • Resetting the fault codes and performing a road test

  • Replacing the oil and filter using the proper oil viscosity for the engine

  • Repairing or replacing the wiring to the camshaft oil control valve for bank 1 exhaust camshaft

  • Replacing the camshaft oil control valve for bank 1 exhaust camshaft

  • Repairing or replacing the timing chain and camshaft phasers as directed by service manual

Additional comments for consideration regarding the P0014 code

If the camshaft timing chain has jumped timing due to worn guides or tensioner failure, this can cause this code. Following the correct diagnostic procedures is required for a proper diagnosis of the timing chain or OCV system.
