Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative terminal of the battery to prevent electrical shock.

2. Remove the Oxygen Sensor

• Locate the Bank 1 Sensor 1 oxygen sensor, which is typically found in the exhaust manifold or upstream of the catalytic converter.
• Use an oxygen sensor socket or wrench to carefully unscrew the sensor from its mounting.
• Disconnect the electrical connector from the oxygen sensor.

3. Inspect and Clean

• Check the electrical connector for corrosion or damage. Clean it with electrical contact cleaner if necessary.
• Inspect the threads of the oxygen sensor for damage; if the sensor is damaged, proceed to replacement.

4. Install the New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor to prevent seizing.
• Screw the new oxygen sensor into place and tighten it to the manufacturer’s specifications (usually around 30-50 lb-ft, but verify in service manual).
• Reconnect the electrical connector to the new oxygen sensor.

5. Reconnect Battery and Clear Codes

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

6. Test Drive

• Start the vehicle and allow it to idle for a few minutes, then take it for a test drive to ensure the check engine light does not reappear.
