- Air intake hoseSearch for my vehicle
- Mass air flow sensorSearch for my vehicle
- Fuel filterSearch for my vehicle
- Fuel pumpSearch for my vehicle

Good to know: Look first for an intake air leak, then the mass air flow sensor, then the fuel pressure.

A code points to a circuit or a function, not a part number: confirm by diagnosis before ordering.
