## Function

• Adjusts the amount of exhaust gas to be recirculated from the exhaust system to the combustion chamber based on the EGR control signal from the PCM.

## Structure/Operation

• Consists of a rotor, coils, and a spring.

• Operates based on the signal from the PCM to drive the EGR valve stepping motor.
• The PCM determines the optimum EGR valve opening angle based on the engine speed and intake air amount when the engine is completely warmed up and drives the EGR valve.
