Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Repair Wiring

Sub-steps:
- Remove the engine cover (if applicable) to access the oxygen sensor wiring.
- Visually inspect the wiring harness for frayed wires, corrosion, or loose connections.
- Repair or replace any damaged wiring or connectors as necessary.

3. Replace Oxygen Sensor

Sub-steps:
- Locate the Bank 1 oxygen sensor (usually located before the catalytic converter).
- Use a socket set to carefully remove the old oxygen sensor.
- Apply anti-seize compound on the threads of the new oxygen sensor.
- Install the new sensor and torque it to the manufacturer's specification (typically around 30-40 lb-ft).

4. Clear Codes and Test

Sub-steps:
- Reconnect the battery.
- Use the OBD-II scanner to clear the P0130 code.
- Start the engine and allow it to reach operating temperature.
- Monitor for any reoccurring codes or issues.
