Learn how to diagnose and fix P0130 oxygen sensor circuit issue in Porsche Cayenne E3. Step-by-step guide with diagnostic procedures and repair instructions.

Solution

1. Preparation

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

2. Inspect and Replace Oxygen Sensor

1. Locate the upstream oxygen sensor (usually before the catalytic converter).
2. Remove the wiring connector from the O2 sensor.
3. Use an oxygen sensor socket to unscrew the sensor from the exhaust manifold.
4. Compare the old sensor with the new one to ensure proper fitment.

3. Install New Oxygen Sensor

1. Apply anti-seize compound to the threads of the new O2 sensor (if not pre-applied).
2. Install the new sensor by hand to avoid cross-threading, then tighten it with the oxygen sensor socket to the manufacturer's specified torque (typically around 30-50 ft-lbs).
3. Reconnect the wiring harness to the new oxygen sensor.

4. Reset Engine Control Unit (ECU)

1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear the P0130 code from the ECU.
3. Start the engine and allow it to reach operating temperature.

5. Test Drive

1. Take the vehicle for a test drive to ensure the check engine light does not return.
2. Monitor engine performance and fuel economy during the drive.
