P0014: causes, symptoms and repairs

The meaning of fault code P0014

P0014 refers to the timing of the camshaft and is only applicable to vehicles that feature a variable valve timing system. The engine control module (ECM) adjusts the camshaft using various control valves. The DTC is triggered when the ECM determines that the camshaft at the rear or on the right of the engine is more advanced than it should be.

Common causes of the fault

  • Using oil that is dirty or has the wrong viscosity. This will cause the oil to break down too quickly or flow too slowly, causing the actuators and other moving components to wear or overheat, and restricting the phasers.
  • Blocked oil passages. The lubrication system can become blocked as contaminants build up over time, particularly if it is not maintained properly.
  • A phaser rotor that gets stuck in the advanced position. This component is responsible for adjusting the position of the camshaft in relation to the crankshaft. If this occurs, the valves will open and close too soon.
  • A stretched, slipping, or worn timing belt or chain. This often causes a lack of synchronisation between the two timing mechanisms.
  • A jammed or faulty oil control solenoid. This obstructs the regulation of the lubrication system, affecting the operation of valve train components.
  • Short circuits, broken wires or oxidised contacts. Affects the power supply for electrical devices.
  • Faulty CKP and CMP sensors. This could affect the transmission of data between the control unit and position sensors.
Symptoms of code P0014

  • Activation of the check engine light
  • Hard starting
  • Frequent stalling, particularly when driving at low speeds
  • A rough engine
  • A decrease in fuel efficiency
  • A failed emissions test
  • Excessive exhaust smoke
  • Shaking or strange noises coming from the engine
Recommended repairs

  • Check the condition of the vehicle motor oil. You can use a clean dipstick to test the oil level and check whether it is time to change the lubricant. Is it dark and sludgy or clean? Is there enough in the reservoir, or does it need to be topped up? If there are clear signs of contamination, drain out the old lubricant and replace it. Car manufacturers typically recommend changing the oil at least once every 12 months. Replace the filter at the same time for better results.
  • If the valve train components or passages are clogged up with contaminants, you can try to unblock them by flushing the engine. This is done using chemical additives. However, this should not be done too frequently as the chemicals can be harsh on the seals and bearings.
  • Inspect the wires and connectors to the sensors and solenoid components for thermal or mechanical damage. If there are cracks or signs of melting, new parts will need to be installed. It may be possible to restore the power supply by cleaning and treating the electrical contacts. The oil control valve itself may need to be replaced.
  • Check the condition and tension of the engine timing belt or chain. Make adjustments or replace the part if necessary. The mechanisms may need to be realigned by installing the sprockets, aligning the timing marks, and lastly reinstalling the tensioner and adjusting the gears.
  • Replace defective position sensors and control valves that cannot be repaired.
Frequently Asked Questions (FAQ)

What does the code “P0014” mean?


It means that the timing of the bank 1 camshaft appears to be too advanced, affecting the engine power and fuel economy.

What causes it to appear?


This could be caused by oil starvation or blockages, a faulty phaser, camshaft or crankshaft position sensor malfunctions, a broken or short circuit, bad timing system components.

How do I get rid of DTC P0014?


You can reset by connecting an OBD2 scanner to the vehicle via the data link connector port and clearing the DTCs. You should take the vehicle for a short test drive afterwards and repeat the scan to determine whether the fault is still there. If it reappears, the vehicle will need to be diagnosed and fixed.
