How to Replace an Exhaust Gas Recirculation (EGR) Control Solenoid

High internal engine temperatures lead to the formation of oxides of nitrogen (NOx) that are smog forming pollutants. The exhaust gas recirculation (EGR) system is used to lower combustion temperatures and reduce NOx emissions. This is accomplished by reintroducing exhaust gases into the engine via an EGR valve.

Some EGR valves are vacuum controlled, some are completely electronic and some are a combination of the two. The hybrid systems often use a remote-mounted EGR control solenoid which is used to apply vacuum to the EGR valve itself. The solenoid is directly controlled by the powertrain control module (PCM).

The typical symptoms of a failed EGR control solenoid include stalling, surging, rough idle, increased emissions, and an illuminated check engine light.

Doug showed up on time for our appointment. He is very knowledgeable and is one of the best mechanics that I have ever come in contact with. I am a retired race car driver and pilot and can spot a phone mechanic very quickly. Doug is the real deal and I would recommend him to anyone. I will be using him again for additional work.

This was the first time using this service and it was very easy. Doug arrived on time and I met him in my office parking lot. So much more convenient than driving to the dealer or dropping my car off at a mechanics shop. Doug is highly competent and I wouldn't hesitate using him again.
