AFTER REPAIRDeal with any faults. Clear the faults from the computer memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
ET047FUEL PUMP CONTROL CIRCUIT
STATUS DEFINITIONACTIVE: This status indicates that the fuel pump is active.
INACTIVE: This status indicates that the fuel pump is inactive.
Conformity check: Engine stopped, ignition on or engine running.
ACTIVEStatus ET047 is ACTIVE when starting the engine. In the event of a fault apply the
interpretation of DF085 Fuel pump relay circuit.
INACTIVEStatus ET047 is INACTIVE when the engine is stopped and the ignition off.

PR139RICHNESS ADAPTIVE OPERATION
PA R A M E T E R
DEFINITIONNo faults must be present.
Conformity check with the engine running and engine coolant temperature > 80°C
Check the sealing of the fuel vapour absorber bleed.
Repair if necessary.
With the engine warm in the idle speed regulation phase, look at parameter PR139.
– If the parameter goes to MAXIMUM stop, there is not enough fuel or too much air in the mixture.
– If the parameter goes to MINIMUM stop, there is too much fuel or not enough air in the mixture.
Check the cleanliness and correct operation of:
– petrol filter,
– petrol pump,
– fuel circuit,
–tank,
– air supply pipe,
– air filter,
– plugs.
Repair if necessary.
Check:
– the compressions,
– the valve clearance,
– the ignition.
Repair if necessary.
