Co oznacza ten kod błędu?
The exhaust camshaft (B) on bank 2 is controlled by the ECM during warm-up after a cold start. The code is set when the camshaft angle sits too far forward compared with the requested position. Poor oil quality, low oil pressure, or a damaged control valve or VVT unit may be behind it.
