Diagnosis & fix steps
Camshaft Position "A" Timing Over-Advanced (Bank 1).
LOGIC: The ECM detects that the camshaft is not at the commanded angle relative to the crankshaft.
ACTION: 1. Check oil level and cleanliness (CRITICAL).
2. Test the VVT Solenoid for sticking.
3. Measure timing chain stretch.
FIX: Change oil/filter; replace VVT Solenoid; replace timing chain/tensioners.
Red Seal field insights
European engines rely heavily on oil pressure for timing. 90% of P0011 codes are caused by extended oil change intervals caking the tiny screens of the VVT solenoid with sludge.
