PR038RAIL PRESSURE
PARAMETER
DEFINITIONThis parameter indicates the rail pressure in bar.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (starting faults, poor performance, stalling etc.),
– after interpretation of command AC225 Rail pressure regulator.
Special notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check: Engine stopped and ignition on
The rail pressure value is between:
0 bar < PR038 < 90 bar if the coolant temperature < 30°C.
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.
Conformity check with the engine running and engine coolant temperature > 80°C
The rail pressure value must be between:
250 bar < PR038 < 290 bar (at idle speed),
1680 bar < PR038 < 1720 bar (full load).
In the event of a fault, refer to the interpretation of fault DF007.
