New EGR Valve Position (EVP) Sensor in Hamilton

What does the EGR Valve Position sensor do?

Exhaust Gas Recirculation (or EGR) systems were introduced to cars as a means of reducing emissions. As their name suggests, they recirculate partially burnt exhaust gases back into the engine where they are re-burnt to reduce emissions and improve fuel economy. As EGR systems became more advanced, the EGR Valve Position sensor was added to optimise the flow of gases back to the engine and improve EGR operation.

The EGR valve position (EVP) sensor is an important part of your car’s EGR system. It detects the position of the valve that allows exhaust gases back into the engine. The position of the valve is then sent to your car’s computer, which adjusts the flow of gases to the valve to create optimum re-burning conditions for exhaust gases.

 

Symptoms of a faulty EGR Valve Position (EVP) sensor:

  • Check engine light on – Usually, the first symptoms of a faulty EGR Valve Position sensor is a check engine light coming on the dash. A faulty sensor will affect the amount of exhaust gas re-entering your engine, affecting combustion and triggering the warning light.
  • Rough running in cold conditions – A faulty EGR Valve Position / EVP sensor may be most noticeable when the engine temperature is low. The engine may struggle to start, stall or idle roughly.
  • Increased emissions – Problems with the EGR Valve Position (EVP) sensor can lead to an increase in exhaust emissions. It is causes excess exhaust smoke then this can lead to your car failing its Warrant of Fitness (WOF) due to excess emissions.

  • Increased fuel use – When the Exhaust Gas Recirculation (EGR) system is not working correctly due to a faulty sensor, gases may not re-enter your engine properly. This will prevent burning, resulting in more fuel going to waste.
