Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes.
Research the codes to identify the corresponding issues (e.g., oxygen sensor failure, catalytic converter issues).

3. Repair or Replace Affected Components

For a faulty oxygen sensor:
- Remove the old sensor: Use the appropriate socket to unscrew the sensor.
- Install the new sensor: Apply anti-seize compound to the threads of the new sensor and torque to manufacturer specifications.
For a loose gas cap:
- Inspect and tighten: Ensure the gas cap is properly tightened or replace if damaged.
For a blocked air filter:
- Remove the air filter housing cover: Unscrew the fasteners and take off the cover.
- Replace the air filter: Install a new filter and reassemble the housing.

4. Clear Error Codes

Return to the OBD-II scanner and clear the error codes.
Disconnect the scanner after clearing codes.

5. Test Drive

Take the vehicle for a short test drive to monitor engine performance.
Observe if the CEL illuminates again after the test drive.
