EGR Control Solenoid: Description and Operation
EGR Control Solenoid Location
The EGR Solenoid Valve is a solenoid operated, computer (ECU) controlled, vacuum switching valve. It functions to limit the operation of the EGR
Valve, by interrupting its vacuum source, upon ECU command. The ECU reads the voltage signal from the coolant temperature sensor, to determine the
engine's operating temperature and determines when to allow EGR valve operation.
