OK, let's start with the basics, as in what the codes mean, so from the OBD II manual for your car:
P0492 Secondary Air Injection System, Bank 2 - Insufficient Flow
Possible cause of fault
- Electrical fault in power supply or line between relay and secondary air injection pump
- Secondary air injection pump relay mechanically faulty
- Mechanical fault in electrical secondary air valve
- Pneumatic secondary air valve faulty/sluggish
- Electrical fault in secondary air injection pump
- Mechanical fault in secondary air injection pump or secondary air injection pump blocked
- Vacuum system leaking
- Air hose to secondary air injection pump slipped off or constricted
P0348 Camshaft Position Sensor 2 – Above Limit
Possible fault cause
- Short circuit to B+
It is likely that the codes are related, especially as the P0348 indicates a possible electrical short, as does the P0492.
