Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to ensure safety.
Raise the vehicle using jack stands for better access to the oxygen sensor.

2. Remove the Oxygen Sensor

Locate the Bank 1 sensor 1 oxygen sensor (usually before the catalytic converter).
Use a socket wrench with an oxygen sensor socket to unscrew and remove the old sensor.
Carefully disconnect the wiring harness from the sensor.

3. Inspect and Clean

Inspect the sensor threads for any carbon buildup or damage.
Clean the mounting area on the exhaust pipe with a wire brush to ensure a proper seal for the new sensor.

4. Install New Oxygen Sensor

Apply anti-seize compound (if recommended) to the threads of the new oxygen sensor.
Install the new sensor by threading it into place and tightening it to the manufacturer's specifications (usually around 30 Nm).
Reconnect the wiring harness securely.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the P0130 code from the ECM.
