Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect and Repair Wiring

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Visually inspect the wiring and connectors leading to the bank 1 sensor 1 oxygen sensor.
3. Repair any damaged wires or replace corroded connectors as needed.

3. Replace Oxygen Sensor

Sub-steps:
1. Locate the bank 1 sensor 1 oxygen sensor, typically found in the exhaust manifold or front pipe.
2. Using an oxygen sensor socket, carefully unscrew the old sensor.
3. Apply anti-seize compound to the threads of the new oxygen sensor.
4. Install the new oxygen sensor, tightening it to the manufacturer’s specified torque (usually around 30 lb-ft).
5. Reconnect the electrical connector to the new oxygen sensor.

4. Clear Codes and Test

Sub-steps:
1. Reconnect the vehicle battery.
2. Use the OBD-II scanner to clear the P0130 code.
3. Start the engine and allow it to reach operating temperature.
4. Take the vehicle for a test drive to ensure proper operation and that the check engine light does not reappear.
