Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fault Codes

Sub-step 1: Clear the fault codes using the OBD-II scanner.
Sub-step 2: Take the vehicle for a test drive to see if the check engine light reappears.
Sub-step 3: If the light returns, note the new codes and proceed to investigate the specific issues related to those codes.

3. Repair or Replace Faulty Components

Sub-step 1: If the fault points to a specific sensor (e.g., oxygen sensor), remove the component using the appropriate socket.
Sub-step 2: Install the new sensor, ensuring proper torque specifications are followed (usually around 30 Nm for oxygen sensors).
Sub-step 3: Reconnect any electrical connectors and check for secure fitment.

4. Reconnect Battery and Final Checks

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the engine and allow it to reach operating temperature.
Sub-step 3: Monitor the dashboard for the engine light and listen for any abnormal sounds.
