What this code means
The intake camshaft on bank 1 is more retarded than commanded. Usually means the VVT system can't advance the cam, often from oil sludge blocking the actuator circuit.

- Oil sludge restricting OCV passages
- Failed oil control valve stuck in retard position
- Low oil pressure or wrong oil viscosity
- Timing chain stretched beyond VVT authority
Symptoms
- Check Engine Light
- Hard cold start
- Rough idle, stalling
- Poor power and fuel economy
Typical fixes
- Oil change—use OEM-specified viscosity
- Clean or replace oil control valve
- Replace timing chain components if worn
