Solution

1. Preparation

Gather tools required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts during repairs.

Record all error codes and refer to the repair manual for specific troubleshooting related to each code.
Clear the codes and see if they return after starting the engine.

3. Inspect and Replace Components

Gas Cap: If the code indicates a fuel system leak, inspect the gas cap:
- Remove and check for cracks; replace if damaged.
- Reinstall and ensure it clicks securely.
Air Filter: If the air filter is clogged:
- Remove the air filter housing cover using a socket set.
- Take out the old air filter and install a new one.
- Reassemble the housing and ensure it is sealed.

4. Vacuum Leak Repair

Inspect all vacuum hoses:
- Replace any cracked or damaged hoses.
- Use a vacuum gauge to test for leaks if necessary.

5. Final Assembly and Testing

Reconnect the battery.
Start the engine and let it idle. Observe for any abnormal sounds or continued warning lights.
Re-scan with the OBD-II scanner to check if any codes return.
