Was bedeutet der Fehlercode?
The engine control module checks that the exhaust camshaft is in the correct position relative to the crankshaft and adjusts the adaptation when it is not. The code concerns bank 2, sensor B, which is the exhaust camshaft, and is set when the adaptation changes too much. It is a component fault with incorrect operation.
Mögliche Ursachen
- Incorrectly set camshafts
- Damaged VVT unit
Was Sie tun können
- 1Read the code, clear it and road test the car to see whether it returns
- 2If you have a diagnostic tool: read the exhaust camshaft adaptation and timing angle for bank 2 in live data with the engine running
- 3Check the engine oil level and quality, and that it is not contaminated
- 4Have a workshop remove the control valve for cleaning and check the oil passages in the cylinder head
- 5If cleaning does not solve the fault: have a workshop fit a new control valve
- 6If the fault returns: have a workshop check the VVT unit
