id0140f1224000
• Consists of an integrated EGR valve position sensor and EGR valve.
• Installed on the upper part of the DC motor.

1 | EGR valve (DC motor)
2 | EGR valve position sensor
3 | Valve

• A potentiometer type has been adopted.
• Detects the fluctuation in voltage (variable resistance) of the valve opening angle and outputs it to the PCM. The voltage input to the PCM increases proportionately to the increase in the valve opening angle.
