EGR VALVE OPENING VALUE REQUIRED
PARAMETER
DEFINITIONThis parameter indicates a theoretical opening value for the EGR valve giving optimum
engine performance.
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.
The EGR valve theoretical opening value for operation with the engine stopped and ignition on is:
- 10 < PR005 < 0%.
In the event of a fault, refer to the interpretation of fault DF272 EGR control circuit.
Conformity check with the engine running and engine coolant temperature > 80°C.
The theoretical EGR valve opening value for operation with the engine running and the engine coolant
temperature > 80°C is 10 < PR005 < 40%.
If there is a fault, refer to the interpretation of fault DF272 EGR control circuit.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
