Diesel Engines Engine
• The EGRVP (EGR Valve Position) sensor is integrated in the DC motor and detects its
position by a sliding contact potentiometer. When the EGR valve opens the resistance of
the potentiometer rises. The sensor supplies the PCM with an analogue voltage signal
between 0…5 V.
NOTE: After the EGR valve is replaced, its adaptation values in the PCM must be reset and
the EGRVP sensor initialized (refer to the section “Control System, Service and
Repair”).
