EGR Control Position Sensor
WARNING: This page is about a different car, the 2024 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
The EGR control valve control position sensor is built in the EGR control valve and uses a permanent magnet and a semiconductor device. This sensor measures valve shaft movements and transmits a voltage signal to ECM. Based on this signal, ECM judges the valve opening angle as of then and controls the motor to achieve opening angle appropriate to the driving conditions.
