P0420 catalytic converter below efficiency
P0011 Camshaft Position 'A' Over-Advanced Or System Performance (Bank 1)
I would first look into p0011 as it may be causing phantom code
- Camshaft timing oil control valve unit has failed
- OCV has failed resistance of the OCV is from 6.9-7.9 ohms room temp,
- Engine valve timing may be out of adjustment
- Check the oil pipe and OCV filter for clogging or a restriction
- Low or dirty oil.
