Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn on the ignition without starting the engine.
Follow the scanner instructions to retrieve and note down any error codes.

3. Address Identified Issues

If a specific code indicates a faulty sensor (e.g., oxygen sensor), replace it:
- Locate the sensor based on the error code.
- Use the socket set to remove the old sensor.
- Install the new sensor and torque to manufacturer specifications.
For codes related to misfires, inspect and replace spark plugs if necessary:
- Remove the ignition coil.
- Unscrew the old spark plug and install a new one, torquing to specifications.

4. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the error codes.
Start the engine and observe if the check engine light remains off.

5. Final Checks

Take the vehicle for a test drive to ensure normal operation.
Monitor for any unusual noises or behavior during the drive.
