Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair Wiring

Sub-steps:
- Visually inspect the wiring harness leading to the oxygen sensor for fraying or damage.
- Use a multimeter to check for continuity in the wires. Repair or replace any damaged wiring.

3. Replace Oxygen Sensor

Sub-steps:
- Remove the oxygen sensor using an oxygen sensor socket or wrench.
- Clean the threaded hole on the exhaust manifold.
- Install the new oxygen sensor, ensuring it is tightened to the manufacturer's specifications (usually around 30 lb-ft).
- Reconnect the wiring harness securely.

4. Clear Codes and Test Drive

Sub-steps:
- Reconnect the negative battery terminal.
- Use the OBD-II scanner to clear the P0130 code.
- Start the engine and allow it to reach normal operating temperature.
- Conduct a test drive to ensure the vehicle operates smoothly and no codes reappear.
