EGR valve stuck open The Exhaust Gas Recirculation (EGR) valve is an important part of your car’s emissions system.It recirculates exhaust from the engine’s combustion chamber to burn again rather than sending it to the emission system, thereby reducing emissions. The EGR valve opens and clo...
then it might be a chance that you have a faulty EGR valve. Although this test may not accurately predict the state of the EGR, if you fail your emission test, it’s a healthy practice to have the vehicle’s EGR valve checked out by a professional. ...
Common EGR valve problems are stuck open or stuck closed. Either way, it can disrupt the exhaust gas treatment process.Bad Mass Air Flow (MAF) sensorA faulty mass air flow sensor will provide an incorrect reading of the air amount entering the engine, leading to an imbalance that results ...
* Exhaust gas recirculation (EGR) during warm-up. The PCM will not allow the EGR valve to open until the engine has warmed up to improve driveability. If EGR is allowed while the engine is still cold, it may cause a rough idle, stalling and/or hesitation. * Evaporative emissions control...
By interpreting these live sensor data, you can address issues beforehand. This leads to better fuel efficiency and enhanced engine performance. It may even extend the life of components like thecatalytic converterandEGR valve. Plus, the live data feature is handy tool to find out the real caus...

Disconnect the PCV valve vacuum line with the engine running. As the engine stumbles, watch the voltmeter reading. It should go down to about 0.2 volts. Reconnect the vacuum line. 8. Open and close the engine throttle with a quick motion ...
mileage. The EGR valve monitors the flow of exhaust gases to the intake manifold and should gradually warm up during normal engine operation. If the EGR valve gets too hot to the touch right after engine start-up, it means that it has stuck in the open position. Replace the EGR valve. ...
low fuel pressure or an EGR valve that is stuck open and leaking exhaust into the intake manifold. If a random misfire code is also accompanied by a P0171 code (cylinder bank 1) or P0174 (cylinder bank 2), it will help isolate the lean fuel condition to one side of the engine or ...
