Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Replace Oxygen Sensor

Tools Required: O2 sensor socket, ratchet and extension, torque wrench, multimeter.
Locate the Bank 1 Sensor 1 oxygen sensor, usually found in the exhaust manifold or front of the catalytic converter.
Remove the electrical connector from the oxygen sensor by pressing the release tab and pulling it off.
Use the O2 sensor socket to unscrew the old sensor from its mounting location.
Safety Warning: Avoid touching the sensor's tip to prevent contamination.
Install the new oxygen sensor by threading it into the exhaust manifold and tightening it to the manufacturer’s specifications (typically around 30 ft-lbs).
Reconnect the electrical connector to the new sensor.

3. Clear Codes and Test Drive

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the P0130 code from the ECU.
Start the engine and allow it to reach operating temperature.
Conduct a test drive under various conditions to ensure the issue is resolved.
