Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Address Error Code

Based on the error code from the OBD-II scanner:
- If related to oxygen sensors:
  - Disconnect the sensor's electrical connector.
  - Remove the sensor using a socket wrench.
  - Install the new oxygen sensor and reconnect the electrical connector.
- If related to the catalytic converter:
  - Inspect for physical damage or blockages.
  - Replace if necessary by unbolting the exhaust components and installing a new catalytic converter.
- If related to misfires:
  - Inspect and replace spark plugs if worn, and check ignition coils for functionality.

3. Repair Vacuum Leaks

Locate the vacuum lines and intake system.
Replace any cracked or damaged hoses.
Use a smoke machine to verify the integrity of the intake manifold and other components.

4. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear the error codes and reset the check engine light.
