Co oznacza ten kod błędu?

The engine control module monitors the exhaust camshaft position and has found that it does not match the commanded position, so the camshaft cannot reach it. The code concerns the control solenoid for the exhaust valve on bank 1. It is a mechanical fault, and camshaft control is switched off.

Możliwe przyczyny

Low engine oil pressure
Poor quality engine oil

3Have a workshop measure the oil pressure
4If you have a diagnostic tool: activate exhaust camshaft control and see whether it responds
