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.
