LAST EGR VALVE OFFSET
PARAMETER
DEFINITIONThis parameter indicates the EGR valve closing ratio for the last EGR valve offset.
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, or engine running, and engine coolant temperature
>80 °C.
The value should be between 10% < PR129 < 40%
