PR157FUEL FLOW SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the fuel flow setpoint in mg/st.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check: Engine stopped and ignition on
The fuel flow setpoint value must be:
PR157 = 0 mg/st (ignition on).
In the event of a fault, consult the interpretation of DF897 Pump pressure regulator circuit.
Conformity check with the engine running and engine coolant temperature > 80°C
Engine running: PR017: Fuel flow = PR157.
In the event of a fault, refer to the interpretation of fault DF897.
