What Is An EGR Valve? | Exhaust gas recirculation EGR valves are a common point of failure on most modern diesel engines. When the valve sticks, it triggers the check engine light and decreases power. Failing seals, a bad actuator, and bad wiring can keep your diesel's EGR valve from functioning. This increases stress on the entire EGR system.
