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.
