Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Electric Exhaust Gas Recirculation (EGR) Valve
Depending on the application, the electric EGR valve is either a water cooled or an air cooled motor and valve assembly. The motor is commanded to move in 52 discrete steps as it acts directly on the EGR valve. The position of the valve determines the rate of EGR flow. The spring works to close the valve against the motor opening force.
