Solution

1. Preparation

Gather tools and parts required for repairs.
Ensure vehicle is parked on a level surface and the engine is cool.

2. Address Error Codes

Sub-step 1: If error codes indicate a specific component failure (e.g., oxygen sensor), locate and prepare to replace that component.
Sub-step 2: Disconnect the negative terminal of the battery to reset the ECU if necessary.

3. Replace Faulty Components

Sub-step 1: For a faulty oxygen sensor:
- Locate the oxygen sensor (usually near the exhaust manifold).
- Use an oxygen sensor socket to remove the old sensor.
- Install the new sensor and tighten it to the manufacturer's specifications (usually around 30 lb-ft).
Sub-step 2: If the gas cap is faulty:
- Remove the old gas cap and replace it with a new one.
- Ensure it clicks into place securely.

4. Clear Error Codes

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Use the OBD-II scanner to clear the error codes from the ECU.

5. Final Checks

Sub-step 1: Start the engine and allow it to reach operating temperature.
Sub-step 2: Monitor for any re-illumination of the check engine light.
