EGRVP (Exhaust Gas
Recirculation Valve Position)
• The EGRVP sensor is a three (3)
wire potentiometer type sensor.
• The PCM 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 PCM monitors EGRP as the
engine is operating to modulate the
EGR valve.
• This is a closed loop function which
means that the PCM continuously
monitors the EGRVP to ensure
proper valve operation.
