1.DEF : Sensor reference voltage too low
2.DEF : Sensor reference voltage too high
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present following a road test or after attempting to start the engine
several times.
Special notes:
If the fault is present:
–the EGR function is inhibited,
–the engine stops,
–the level 2 warning light is lit,
–the OBD warning light will come on after three consecutive driving cycles (starting
+ 5 seconds + switching off the ignition and waiting 1 minute).
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
The sensors connected to supply no. 3 are:
–Rail pressure sensor.
–Air flow sensor..
To locate a faulty sensor and/or connection, disconnect one of these sensors then check whether the fault
becomes stored.
If the fault is still present, repeat the operation with the other sensors.
(Wait a few seconds after each disconnection so that the computer can carry out the check).
If the fault is stored after a disconnection, replace the faulty sensor or repair its connection.
Clear the faults created by the multiple disconnections.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults:
Only deal with this fault if it is stored.
Special notes:
The injection control unit supply relay (50A) is located on the relay plate in the
engine connection unit, under the Protection and Switching Unit.
If the fault is present, the level 1 warning light is lit.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the Protection and Switching Unit connections.
Check the injection computer connections.
Repair if necessary.
Check the condition of the battery terminals making sure they are correctly tightened.
Check the condition of the injection supply relay and its mounting.
Check the 5D (5A) + after ignition feed injection fuse located on the UPC.
Repair if necessary.
Check the continuity, and absence of interference resistance of the following connection:
Injection computer brown 48-track connector B
track E1Track 2 injection supply relay mounting
Repair if necessary.
If the fault is still present, contact the Techline.
IMPORTANT!WARNING
If the UPC does not detect the injection computer frames the engine fan assembly 1
will be switched on until the battery is completely discharged.
In the event that engine cooling fan 1 is not working, GMV 2 will be supplied.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Special notes:
It is difficult or even impossible to start the engine when cold.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the pre-postheating unit connections.
Check the connections on all the heater plugs.
Repair if necessary.
Check fuse F2 (70A) on the power supply fuse board.
Check the resistance of the heater plugs:
Replace any plug whose resistance is not below 2 Ω at + 20˚C.
Check the continuity and absence of interference resistance of the following connections:
preheating unit track 1 cylinder 3 heater plug
preheating unit track 2 cylinder 1 heater plug
preheating unit track 6 cylinder 4 heater plug
preheating unit track 7 cylinder 2 heater plug.
Check for presence of + 12 V on track 4 of the pre-postheating unit (via fuse F2, 70A).
If the fault is still present,
Check the injection computer connections.
Check the following connections for continuity and make sure there is no extraneous resistance:
Injection computer grey 32-track connector C, track A4 track 3 preheating unit connector
Injection computer grey, 32-track connector C, track E2 track 8 of the preheating unit connector
