EGR VALVE POSITION FEEDBACK LOOP DIFFERENCE
PARAMETER
DEFINITIONThis parameter indicates the percentage difference between the setpoint and the EGR
valve position.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on.
PR022 = PR005 EGR valve opening setpoint – PR051 EGR valve position feedback
In the event of a fault, consult the interpretation of fault DF118 EGR solenoid valve servo-control.
Conformity check with engine running, engine coolant temperature > 80°C.
PR022 = PR005 “EGR valve opening value required” – PR051 “EGR valve position feedback”
At idle speed the value should be close to 0.
In the event of a fault, consult the interpretation of fault DF118 EGR solenoid valve servo-control.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

repair, Wiring: Precautions for repairs), repair the wiring; otherwise replace the wiring.
Pedal sensor connected, vehicle ignition on and engine stopped:
– check the value of PR030:
0% no load,
100% full load,
