Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Retrieve and Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes.
Research codes to determine potential causes, focusing on common issues such as oxygen sensor failure or catalytic converter problems.

3. Perform Necessary Repairs

For an oxygen sensor replacement:
1. Locate the faulty oxygen sensor (usually in the exhaust system).
2. Disconnect the sensor's electrical connector.
3. Use an oxygen sensor socket to remove the old sensor.
4. Install the new sensor and reconnect the electrical connector.
For a catalytic converter issue:
1. Inspect the exhaust system for obstructions or signs of damage.
2. If replacement is needed, unbolt the catalytic converter from the exhaust system.
3. Install the new catalytic converter, ensuring proper alignment and sealing.

4. Reset the Check Engine Light

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

5. Test Drive

Start the engine and allow it to idle for a few minutes.
Go for a short test drive to ensure that the check engine light remains off and that the vehicle operates smoothly.
