Co oznacza ten kod błędu?
On bank 2 this code is set when, during warm-up after a cold start, the camshaft stands further back than the requested position. Poor oil quality, low oil pressure, and a fault in the control valve or the VVT unit may be behind it.
Możliwe przyczyny

- 4If you have a diagnostic tool, read the camshaft position for bank 2 in live data during warm-up and compare it with the requested position
- 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 control valve and the VVT unit on bank 2
