STATUS
DEFINITION
ACTIVE: This status indicates that the recirculated exhaust gas cooling setpoint
is active.
INACTIVE: This status indicates that the recirculated exhaust gas cooling setpoint
is not active.
NOTESNone.
Conformity check: Engine stopped and ignition on and Engine running and engine coolant
temperature > 80°C
This status gives a setpoint for status ET587 Recirculated exhaust gas cooling. This programming changes
depending on the computer.
In the event of a fault, see the interpretation of faults DF209 EGR valve position sensor circuit and DF647 EGR
valve position regulation.

PR022EGR 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: Engine stopped and ignition on
This parameter indicates the percentage difference between the setpoint and the EGR valve position.
In the event of a fault, consult the interpretation of faults DF209 EGR valve position sensor circuit and DF647
EGR valve position regulation.
Conformity check with the engine running and engine coolant temperature > 80°C
The PR022 value must be between:
- 5% < PR022 < + 5%.
In the event of a fault, refer to the interpretation of faults DF209 and DF647.

PR030ACCELERATOR PEDAL POSITION
PARAMETER
DEFINITIONThis parameter indicates the accelerator pedal position as a percentage.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (e.g. lack of power, etc.).
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
If no pressure is being applied to the pedal PR030 = 0%.
In the event of a fault, consult the interpretation of DF196 Pedal sensor circuit gang 1 or DF198 Pedal sensor
circuit gang 2.
Sensor electrical conformity
Check the continuity and absence of interference resistance of the following connections:
–3LR between components 120 and 921,
–3LS between components 120 and 921,
–3LT between components 120 and 921,
–3LU between components 120 and 921,
–3LW between components 120 and 921,
–3LV between components 120 and 921.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.

CONTINUED
The accelerator pedal sensor should be connected, the vehicle should have the ignition on and the engine
switched off:
– Check that the accelerator pedal value is:
PR030 = 0%: no load,
100% < PR030 < 120%: full load,
135% < PR030 < 145%: full load after pedal kickdown point.
If the value is not correct, replace the pedal sensor.
