how to fix P0130 oxygen sensor circuit malfunction in BMW X3 F25 (2011-2018)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle battery to ensure safety while working on electrical components.
• Allow the engine to cool before starting work.

2. Locate and Remove the Oxygen Sensor

• Locate the affected oxygen sensor (usually upstream of the catalytic converter).
• Use a socket wrench with an oxygen sensor socket to carefully remove the sensor from the exhaust pipe.
• Disconnect the electrical connector from the oxygen sensor.

3. Inspect and Replace

• Inspect the old oxygen sensor for damage or contamination.
• If necessary, clean the threads of the oxygen sensor port on the exhaust with a wire brush.
• Install the new oxygen sensor, ensuring the threads are clean and free of debris.
• Torque the sensor to the manufacturer's specifications (typically around 30 Nm or 22 lb-ft).

4. Reconnect Electrical Connections

• Connect the electrical connector to the new oxygen sensor securely.
• Ensure there are no loose wires or damaged connectors.

5. Reconnect Battery and Test

• Reconnect the vehicle battery.
• Start the engine and allow it to reach operating temperature.
• Monitor the oxygen sensor readings with an OBD-II scanner to ensure it is functioning correctly.
