Defect modes
Motorised throttle valve
In defect mode, the motorised throttle valve can have 6 different statuses.
Type 1
The throttle opening is less than the Safe mode position. The throttle is no longer activated and is
automatically in Safe mode. The ESP, distance control and cruise control/speed limiter systems are
disabled. The automatic transmission is in "Safe mode".
Type 2
The throttle opening is no longer actuated. The engine speed is limited by injection cut-off.
Type 3
Defect mode is associated with restructuring of the pedal setpoints (constant pedal setpoint for each gear).
Type 4
The associated defect mode restricts the throttle opening. The maximum throttle valve opening threshold
results in a speed below 54 mph (90 km/h).
Type 5
The computer no longer processes torque changes requested by the ESP, distance control, cruise control/
speed limiter and automatic gearbox systems.
This defect mode results from a computer malfunction, or a fault with the manifold or turbocharging
pressure sensor.
The system then only uses the accelerator pedal signal.
The ESP, distance control and cruise control/speed limiter systems are disabled. The automatic
transmission system is in Safe mode.
Type 6
The turbocharging valve no longer works.

NOTESPriority for dealing with a combination of faults:
Deal with faults DF084 Actuator relay control circuit or DF046 Battery voltage first
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running.
Run a multiplex network test (see88B, Multiplex).
If the fault is still present, carry out fault finding on the automatic transmission system (seeMR 364, Mechanics,
21B, Sequential gearbox).
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

The fault is declared present with the engine running and a road speed above 36 mph
(60 km/h).
Special note:
The acquisition is made if the vehicle is not fitted with an automatic transmission.
Check the cleanliness, condition and assembly of the clutch pedal switch and its connections.
Repair if necessary.
If the fault is still present, disconnect the switch. Check that when the clutch pedal is depressed, the switch is active,
and that when the clutch pedal is released, that the switch is not active and that the recommendations regarding
clutch pedal clearance are still valid (see MR 364, Mechanics,20A, Clutch
Replace the switch if necessary.
If the fault is still present, manipulate the harness so that the status changes (present  stored).
Look for any damage to the wiring harness, and check the condition and connection of the injection computer
and clutch pedal switch connectors.
Repair if necessary.
If the fault is still present, check the earth on track 2 of the switch.
If there is no earth on track 2, check the insulation, continuity and the absence of interference resistance on
the following connection:
Clutch pedal switch track 2 earth
Repair if necessary.
If the fault is still present, check the insulation, continuity and the absence of interference resistance on the
following connections:
Clutch pedal switch track 1 Track C4, connector A, of the computer
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.
