What are the symptoms of a faulty EGR?
1 Answers
EGR valve failure may cause symptoms such as extremely unstable idling or even stalling, flashing malfunction indicator light, failure to meet annual emission inspection standards, burning engine oil, and blue exhaust smoke. Here is some information about the EGR valve: 1. The EGR valve is part of the exhaust gas recirculation system. When the EGR valve remains open, the car may exhibit black smoke, poor acceleration, and increased fuel consumption. When the EGR valve remains closed, it can affect the vehicle's exhaust emissions, potentially causing it to fail the annual inspection. 2. The function of the exhaust gas valve is to appropriately reduce fuel consumption, improve engine efficiency, lower exhaust temperature, and decrease the formation of nitrogen oxides and carbon monoxide.
