how to fix P0130 code in Volkswagen Golf Seventh Generation (2013-2020)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool down before starting work.

2. Inspect Oxygen Sensor

• Locate the Bank 1 Sensor 1 oxygen sensor (typically in the exhaust manifold).
• Disconnect the sensor's electrical connector.
• Visually inspect the sensor and its wiring for any signs of damage or wear.

3. Test Oxygen Sensor

• Using a multimeter, set it to measure voltage.
• Reconnect the sensor temporarily and start the engine.
• Measure the voltage output at the sensor’s connector. A healthy sensor should oscillate between 0.1V to 0.9V.
• If the voltage is stable or out of range, the sensor may need replacement.

4. Replace Oxygen Sensor (if necessary)

• If testing indicates a faulty sensor, proceed with replacement:
  • Use an oxygen sensor socket to remove the old sensor.
  • Apply anti-seize compound to the threads of the new sensor (if applicable).
  • Install the new sensor and torque it to the manufacturer’s specifications (typically around 30 lb-ft).
  • Reconnect the electrical connector.

5. Clear Codes and Test

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear any stored trouble codes.
• Start the engine and allow it to reach operating temperature.
• Conduct a test drive to monitor the vehicle's performance and ensure the check engine light does not re-illuminate.
