For any persistent codes, address the specific issues indicated (e.g., replace faulty sensors, repair wiring).

3. Inspect and Repair Components

Fuel System:
- Check fuel pressure with a fuel pressure gauge; replace the fuel pump if pressure is low.
- Clean or replace fuel injectors if they are clogged.
Electrical Connections:
- Tighten any loose connectors and repair any damaged wiring.
- Replace any faulty sensors based on the DTCs retrieved.
Exhaust System:
- Inspect the exhaust for leaks; replace gaskets or components as necessary.
- Ensure that the catalytic converter is functioning correctly; replace if needed.
