    What does this fault code mean?

    Exhaust camshaft control is too slow: the engine control module requests a position, and if the exhaust camshaft has not reached it within a set time, the fault is registered. The check takes place while the engine is running and camshaft control is active.

    Possible causes

    • Low oil pressure
    • Poor engine oil quality or contamination in the oil
    • Damaged or sticking reset valve for the exhaust camshaft
    • Mechanical fault inside the VVT unit

    What you can do

    1. 1Check the fuse that feeds the camshaft reset valve
    2. 2Check the oil level and oil condition, particularly for contamination
    3. 3With a diagnostic tool: compare the actual and requested exhaust camshaft positions in live data as the engine speed rises
    4. 4Have a workshop measure the oil pressure, clean the reset valve and check the oil passages in the cylinder head
    5. 5If none of this finds the cause, have a workshop replace the reset valve or check the VVT unit

    Symptoms you may notice4

    • The check engine lamp lights up or behaves abnormally
    • The engine is slow to start or cranks slowly
    • The engine performs poorly and lacks power
    • The engine hesitates, surges or runs unevenly

    What the fault can affect1

    • Camshaft control for the exhaust valves is switched off

    General guidance for car owners. Diagnosis on the car can point to a different cause.
