EGR Valve: Description and Operation
Exhaust Gas Recirculation Valve Control and Valve Position Sensor
Exhaust Gas Recirculation Valve Control And Valve Position Sensor
The Exhaust Gas Recirculation Valve Control controls the amount of exhaust gases recirculated back to the intake. It is a proportional solenoid with a
built-in position sensor. The Valve Position Sensor is needed to give the control circuit feedback to achieve desired travel position. The Exhaust Gas
Recirculation Valve Position Sensor is a variable resistance pintle position sensor that makes position measurements of the exhaust gas recirculation
valve control actuator. Input signals from the manifold absolute pressure (MAP) and barometric pressure (BARO) sensors are used by the PCM to
calculate and control the EGR system flow.
