Electric Exhaust Gas Recirculation (EGR) Valve
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2019 Lincoln Navigator, 2019 Lincoln Nautilus, 2019 Lincoln MKZ, 2019 Lincoln MKT, and 2019 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
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.
