In the event of rail overpressure:
Check that the injectors are operating correctly (see Component test, Test 1, Injector Test).
Check that the rail pressure sensor is operating correctly using command AC011 Rail pressure regulator.
Display parameter PR038 Rail pressure, and refer to the conformity check to check the operating values.
If these checks do not indicate any abnormality and if the fault is still present, replace the injection pump.
in the event of rail underpressure:
Check that the rail pressure sensor is operating correctly using command AC011 Rail pressure regulator.
Display parameter PR038 Rail pressure, and refer to the conformity check to check the operating values.
Check the low pressure diesel circuit priming.
Check the conformity of the diesel filter connections.
Check the condition of the filter (clogging and water saturation).
Check that there are no air bubbles between the filter and the high pressure pump.
Check the low and high pressure diesel fuel circuit sealing (visual inspections, odour, etc.): pump housing,
pressure relief valve, pipes, rail and injector unions, injector wells, etc.
Check that the injectors are operating correctly (see Component test, Test 1, Injector Test).
Carry out the necessary operations.

STOREDWATER IN DIESEL FUEL DETECTOR CIRCUIT
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine is started or following a road test.
A) Make sure the water in diesel fuel detection sensor is properly connected.
– If not, clear the fault,
– carry out a road test (speed > 12 mph (20 km/h) at an engine speed of> 1200 rpm) for more than 30 seconds.
– If the fault does not recur, end the fault finding procedure.
– If the fault does recur, go to step B.
B) If the sensor is properly connected:
– drain the diesel filter unit (seeMR 364, 13A, Fuel supply),
– clear the fault,
– carry out a road test (speed > 12 mph (20 km/h) at an engine speed of> 1200 rpm) for more than 30 seconds.
If the fault does not recur, end the fault finding procedure.
C) If the fault recurs:
–Check the continuity and the absence of unwanted resistance on the connection between:
Injection computer, grey 32-track connector C, track A2 Track 3 of the water detection sensor
–Check the power supply to the water detection sensor:
UPC PPM1 black connector track 2 Track 1 the water detection sensor
Earth Track 2 water detection sensor
– Carry out the necessary repairs.
If none of these checks reveal any faults:
– Replace the water detection sensor (see MR 364, 13A, Fuel supply).
– Clear the fault.
– Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds,
to confirm the repair.
Note:
if the level of water in the fuel filter unit is lower than the sensor electrodes, certain driving conditions (on a bend,
leaning) may causethe injection warning light to light up erratically.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.
