Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Remove the Oxygen Sensor

• Connect the electrical connector to the new sensor, ensuring it clicks securely.

5. Reconnect Battery and Test

• Reconnect the vehicle's battery.
• Start the engine and allow it to reach operating temperature.
• Check for any exhaust leaks around the sensor area.
