CONTINUED 1
Reconnect the fuel flow solenoid valve
connector; before restarting the engine, switch
off the ignition and wait 30 seconds.
Remove the connector for the fuel pressure
solenoid valve (white), does the engine stop?
YES
Reconnect the connector of the fuel pressure
solenoid valve, switch off the ignition and wait for
30 seconds.
Check that the oil level is correct and that the
engine coolant temperature is greater than 60°C.
Engine running at idle speed.
– Run command AC029 High pressure circuit
sealing test.
The engine will perform 4acceleration cycles.
– Refer to parameters PR008 Rail pressure
setpoint and PR038 Rail pressure.
–Does PR038 Rail pressure follow PR008 Rail
pressure setpoint during the phase of the
4acceleration cycles?
NO
NOReplace the pump (the fuel pressure
solenoid valve remains closed
mechanically).
YESCheck the injectors by carrying out Te s t 6.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

Restore parameters PR063 Fuel temperature and PR064 Coolant temperature.
Fuel temperature reference value when operating at idle speed is between 60 °C and 80 °C.
The coolant temperature reference value is between 80 °C and 90 °C.
Note:
– when the fuel temperature is above 120°C, the maximum rail pressure is reduced to protect the plastic pipes,
– when the coolant temperature is above 100°C, the maximum rail pressure is reduced to protect the engine.
Are the fuel and coolant temperatures within the
reference value range?
YES
NOCheck the coolant temperature (see the
interpretation of DF001 Coolant
temperature sensor circuit) and fuel
temperature sensors (see the
interpretation of DF098 Fuel temperature
sensor circuit).
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

Restart the engine and let it idle.
Refer to PR064 Coolant temperature and wait
until the temperature is above 60°C.
Refer to the parameters
PR364 Cylinder no. 1 fuel flow correction.
PR365 Cylinder no. 4 fuel flow correction.
PR405 Cylinder no. 2 fuel flow correction.
PR406 Cylinder no. 3 fuel flow correction.
Are the reference values 1 (tolerance - 0.7/+ 0.9)?
NO
If the reference values are 0.3 or 1.9,
check the engine compression.
Is the compression in order?
NO
Engine fault.
YESDisconnect the return system connections
at the injectors and close off the return
pipes so they are leak-tight (pipe and can
kit for engines1711 and 1771).
While the engine is idling, check the return
flow rate at the injector.
After 5minutes the return volume should
be between 16 ml and 30 ml per injector.
Is the return volume between this interval?
Injector OK
Contact the Techline.
NO
YES
YESReplace the
faulty injector.
Check that the
fault is not
due to the
presence of
two heat
protection
washers.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
