Note:
Supply no.2 is for the following components:
– pedal sensor (gang 2),
– EGR valve position sensor,
– cruise control/speed limiter button (on steering wheel),
– refrigerant pressure sensor.
Measure the feed voltage on the following sensors:
– Connection code 3LU of component 921.
– Connection code 3AAQ of component 1290.
– Connection code 3GC of component 1460.
– Connection code 38Y of component 1202.
If the voltage is more than + 5.1 V, disconnect the sensor connectors one by one.
If, after disconnecting the pedal sensor, the voltage returns to normal,
Check the insulation against + 12 V of the following connection:
– connection code 3LU, between components120 and 921.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If, after disconnecting the EGR valve, the voltage returns to normal,
Check the insulation against + 12 V of the following connection:
– connection code 3GC between components 120 and 1460.
If, after disconnecting the differential pressure sensor, the voltage returns to normal,
Check the insulation against + 12 V of the following connection:
– connection code 3AAQ between components 120 and 1290.
If the voltage returns to normal after the coolant pressure sensor is disconnected,
Check the insulation against + 12 V of the following connection:
– Connection code 38Y between components 120 and 1202.
If the fault is still present, check the conformity of ET413 Cruise control/speed limiter function
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Clear the faults created by the multiple disconnections.
Carefully examine the engine management computer connections (for conductive particles, bent pins).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

The fault is declared present after:
– engine speed is between idling speed and 1050 rpm PR055 Engine speed,
–PR064 Coolant temperature ≥ 50°C.
Priorities when dealing with a number of faults:
Apply the interpretation of faults DF026 CYLINDER 1 INJECTOR CONTROL
CIRCUIT and DF249 Injector control first if they are present or stored.
Special notes:
Check that the stored injector codes are consistent with those engraved on each
injector. If not, run command SC002 Enter injector codes and follow the procedure,
After an injector has been replaced, run command SC002 Enter injector codes and
command SC036 Reintialise programming and follow the procedure.
IMPORTANT
Possible absence of combustion on one cylinder even though the injector is properly
fed.
