1. 1Scan the vehicle’s OBD-II system to confirm the P0131 code and check for any additional codes.
2. 2Inspect the wiring and connectors leading to the upstream O2 sensor for damage, corrosion, or loose connections.
3. 3Measure the voltage output of the upstream oxygen sensor using a multimeter to ensure it is within the specified range.
