NOTESPriority for dealing with a combination of faults:
In the event of a fault DF154, DF119 Camshaft sensor signal and DF080 Camshaft
dephaser circuit, ignore fault DF080 and deal with the other 2 faults first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the starter motor has been running for 10 seconds
or at an engine speed above 600 rpm.
Special note:
–OBD warning light illuminated.
Check the cleanliness, condition and the assembly of the flywheel.
Repair if necessary.
If the flywheel has been replaced or removed, the flywheel target has to be reinitialised, then reprogrammed.
Programming reinitialisation:
Run command RZ005.
Carrying out the flywheel target programming:
Accelerate up to 4000 rpm in third gear then decelerate, foot off the pedal, to power take-up speed*.
Then repeat immediately.
In rare cases, fault DF125 Torquemeter programming may appear.
(*This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque).

NOTESPriority for dealing with a combination of faults:
Apply the procedure for dealing with faults DF081 Solenoid valve canister bleed and
DF085 Fuel pump relay first if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after an attempt is made to start the engine.
Special note:
–OBD warning light comes on.
Check the cleanliness, condition and fitting of the fuel vapour absorber.
Repair if necessary.
If the fault is still present, adjust the harness so that the fault status changes (present  stored).
Look for any damage to the wiring harness, and check the condition and connection of the injection computer
and fuel vapour absorber connectors.
Repair if necessary.
If the fault is still present, check for the +12V on track 1 of the fuel vapour absorber.
If the +12V is not present, check the following connection for insulation, continuity and the absence of
interference resistance:
Fuel vapour absorber track 1 track 2 of connector PPM1 on the Protection and Switching Unit
Repair if necessary.
If the fault is still present, disconnect the battery and the injection computer.
Check the insulation, continuity and the absence of interference resistance on the following connection:
Computer, connectorC, track E1petrol vapour absorber track 2
Repair if necessary.
If the fault is still present, measure the resistance between tracks 1 and 2 of the fuel vapour absorber bleed
solenoid valve.
Replace the bleed solenoid valve for the fuel vapour absorber if the resistance is not 26 ±4 at 23 °C.
If the fault is still present, check the insulation, continuity and the absence of interference resistance on the
following connections:
Computer, connectorC, track D1 track 1 of the PEM connector of the Protection
and Switching Unit
Repair if necessary.
If the fault is still present, deal with the other faults, then proceed to the conformity check.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.
