Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Allow the engine to cool before proceeding with repairs.

2. Inspect and Repair Wiring

Visual Inspection: Check the wiring harness connected to the oxygen sensor for any visible damage or wear.
Connector Check: Ensure the connector is securely fastened and free from corrosion. Clean if necessary.
Repair: If damaged wiring is found, repair or replace the affected sections using appropriate automotive wire and connectors.

3. Oxygen Sensor Replacement

Remove Old Sensor:
- Use an oxygen sensor socket to carefully unscrew the bank 1 sensor 1 from the exhaust manifold.
- Be cautious of exhaust heat and debris.
Install New Sensor:
- Apply anti-seize compound to the threads of the new oxygen sensor (if not pre-applied).
- Thread the new sensor into the exhaust manifold and tighten it to the manufacturer’s specifications (usually around 30-40 lb-ft).
Reconnect: Reattach the electrical connector to the new sensor, ensuring a secure fit.

4. Reconnect Battery and Clear Codes

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

5. Test Drive

Take the vehicle for a test drive under various conditions to ensure the check engine light does not reappear and that the engine operates smoothly.
