  • Possible overheating of the engine

  • Irregular engine idle or stalling

Possible Causes:

  • Malfunctioning or faulty exhaust gas temperature sensor

  • Damaged or corroded wiring in the sensor circuit

  • Poor electrical connection at the sensor

  • Exhaust system leaks or damage

  • Engine running at excessively high temperatures

Related Parts:

  • Exhaust Gas Temperature Sensor: Exhaust gas temperature sensor monitors the temperature of the exhaust gases. This car's malfunctioning valve will lead to higher emissions & lower performance

Possible Solutions:

  • Inspect and replace the exhaust gas temperature sensor, if necessary

  • Check the wiring and connectors in the sensor circuit for any signs of damage or corrosion

  • repair or replace as needed

  • Ensure a proper electrical connection at the sensor

  • Inspect the exhaust system for leaks or damage

  • repair or replace as necessary
