Description:

  • Issue detected with the temperature sensor in the Exhaust Gas valve

Possible Symptoms:

  • In some cases, there may be performance problems, such as pinging on acceleration, when the engine is under load or when driving the vehicle at higher speeds

Possible Causes:

  • Restriction in the Exhaust Gas Recirculation (EGR) passages, usually caused by carbon buildup

  • The EGR Valve is defective

  • Lack of proper vacuum or electrical signal to the EGR valve

  • Malfunctioning EGR Vacuum supply solenoid

  • Lack of proper EGR system feedback to the computer

Related Parts:

  • Exhaust Gas Recirculation (EGR) Temperature Sensor: Exhaust gas recirculation (EGR) is an emissions reduction technique used in petrol and diesel engines. EGR Temperature sensor monitors the temperature in the emission system. This car's malfunctioning sensor will lead to higher emissions & lower performance

Possible Solutions:

  • Before replacing any parts try cleaning the EGR valve, tube and passages.
