EGRVP (EGR Valve Position)
• The EGRVP sensor is a three (3) wire potentiometer type sensor.
• The ECM supplies a 5 volt reference voltage that the
EGRVP uses to produce a linear analog voltage that
indicates the amount of movement of the valve.
• The ECM monitors EGRVP as the engine is
operating to modulate the EGR valve.
• This is a closed loop function which means that the ECM
continuously monitors the EGRVP to ensure proper valve position.
