NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault declared present before an attempt is made to start the engine it will not be
possible to start the engine.
Use bornier Ele. 1681 for all operations on the injection computer connectors.

NOTESPriority when dealing with a number of faults:
In the event of more than one fault:
–DF056 Air flow sensor circuit,
–DF057 Water in diesel fuel detector circuit,
–DF067 Damper control circuit,
Check the conformity of the + 12 V after relay supply line,
from track 2 of the UPC PPM1 connector.
(Use the Wiring Diagrams Technical Note for the vehicle).
Check the camshaft sensor connectors,
Check the injection computer connections.
Check that the camshaft sensor is correctly positioned and mounted.
Also check the general condition (damaged housing, heating up, etc.).
Carry out the necessary repairs.
Check the continuity and absence of interference resistance of the following connections:
Injection computer brown 48-track connector B, track D1 Track 2 Camshaft sensor
Injection computer brown 48-track connector B, track A1 Track 1 Camshaft sensor
Repair if necessary.
Check the camshaft sensor resistance between tracks 2 and 3.
If the resistance is not 10250Ω ±500 at 20°C, replace the sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present following a road test or after attempting to cold start the
engine.
Special notes:
– Use bornier Ele. 1681 for all operations on the injection computer connectors.
– The default value given by the diagnostic tool is 100°C.
CC.0
NOTESNone.
Check the fuel temperature sensor connections.
Check the injection computer connections.
Repair if necessary.
Measure the resistance of the fuel temperature sensor across tracks 1 and 2.
Replace the fuel temperature sensor if the resistance is not: 2050Ω ± 100 at 25°C
810Ω ± 47 at 50°C
309 Ω ± 17 at 80°C
Check the continuity and insulation from earth of the following connections:
Injection computer brown 48-track connector B, track H2 Track 1 fuel temperature sensor
Injection computer grey 32-track connector C, track F1 Track 2 fuel temperature sensor
If the fault is still present, replace the fuel temperature sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.
