what does it mean when my Volkswagen Golf MK6 (2009-2014) shows P0130 code

Solution

1. Preparation

• Gather tools and parts needed for repair.
• Disconnect the battery to ensure safety.
• Raise the vehicle using jack stands for better access to the oxygen sensor.

2. Remove the Oxygen Sensor

• Locate the Bank 1 sensor 1 oxygen sensor (usually before the catalytic converter).
• Use a socket wrench with an oxygen sensor socket to unscrew and remove the old sensor.
• Carefully disconnect the wiring harness from the sensor.

3. Inspect and Clean

• Inspect the sensor threads for any carbon buildup or damage.
• Clean the mounting area on the exhaust pipe with a wire brush to ensure a proper seal for the new sensor.

4. Install New Oxygen Sensor

• Apply anti-seize compound (if recommended) to the threads of the new oxygen sensor.
• Install the new sensor by threading it into place and tightening it to the manufacturer's specifications (usually around 30 Nm).
• Reconnect the wiring harness securely.

5. Reconnect Battery and Clear Codes

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