What does this fault code mean?
During catalyst warm-up after a cold start the ECM controls the camshaft position, which is adjusted by the VVT unit. The code is set when the camshaft angle on bank 1 is more advanced than requested. Poor engine oil, low oil pressure, or a fault in the camshaft control valve or the VVT unit may be behind it.
Possible causes
- Poor engine oil quality
- Low oil pressure
- Damaged camshaft control valve
- Damaged VVT unit
What you can do
- 1If a fault code for the correlation between crankshaft and camshaft position is stored, diagnose it first
- 2Check that the engine oil is clean, of the right quality, and that the oil level is correct
- 3If you have a diagnostic tool, read the actual and requested camshaft position in live data during warm-up and check that they follow each other
- 4If the oil is contaminated, have a workshop change the oil and check whether the VVT unit has been damaged
- 5Clear the code and road test the car with the engine cold to see whether it returns
- 6If the code returns, have a workshop with diagnostic equipment check the camshaft control valve and the VVT unit
Symptoms you may notice5
- Uneven idle
- Reduced performance
- The engine misfires
- The car feels weak or lacks power, especially when setting off from standstill
- The car hesitates or surges, or runs unevenly
