STOREDMOTORISED THROTTLE CONTROL CIRCUIT
CC.1 : short circuit to + 12 V
1.DEF : Motorised throttle general control fault
WARNING
Never drive the vehicle without having confirmed that no faults involving the throttle valve are present.
NOTESPriority for dealing with a combination of faults:
If faults DF095 Throttle potentiometer circuit gang 1 or DF096 Throttle
potentiometer circuit gang 2 are present, deal with these first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– a change in engine speed,
– the air temperature must be between 5°C and 105°C inclusive.
Special note:
–level 1 fault warning light illuminated.
– throttle valve defect mode types 1, 2 and 6.
Check the cleanliness and condition of the throttle valve and its connections.
Manually check that the throttle rotates properly.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier, check for insulation and continuity on the following connections:
Computer, connector B, track M3 Track 4 of the motorised throttle
Computer, connector B, track M4 Track 3 of the motorised throttle
Computer, connector B, track G4 Track 1 of the motorised throttle
Repair if necessary.
Measure the resistance of the throttle motor between tracks M3 and M4 of the computer.
Replace the throttle valve if the resistance is not 1.57 at 23°C.
If the fault is still present, deal with the other faults then proceed to the conformity check.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

MOTORISED THROTTLE VALVE SERVO
1.DEF : motorised throttle stop search fault
2.DEF : motorised throttle rest position programming error
3.DEF : motorised throttle servo fault
4.DEF : the position memory function does not work
5.DEF : when the throttle bounces off the lower stop, a relatively large permanent
discrepancy can be seen between the set position and actual position of the throttle.
The bounce detection is based on this error. The oscillation fault, after N oscillations
detected, activates the Limp Home defect mode.
6.DEF : when there is a micro-break on gang 1 of the sensor, the voltage delivered
is minimal (0V), which broadly corresponds to complete throttle closure. We can then
see the gang 1 signal lapse in relation to the gang 2 signal, which remains correct.
This lapse speed of one gang in relation to another is used to detect micro-breaks.
The micro-break fault does not activate any defect mode or illuminate any warning
lights.
7.DEF : non-compliance with emission control standards
NOTESPriority for dealing with a combination of faults:
Apply the procedure for dealing with faults DF011 Sensor supply voltage no. 1,
DF078 Throttle potentiometer control circuit, DF095 Throttle potentiometer
circuit gang 1 and DF096 Throttle potentiometer circuit gang 2 first if they are
present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– A change in engine speed.
– the air temperature must be between 5°C and 105°C inclusive.
Special note:
If 1 DEF, 2.DEF or 3.DEF:
– the OBD warning light is lit,
– throttle valve defect mode types 1, 2 and 6.
If 4.DEF or 5.DEF:
– the OBD warning light is lit,
– Throttle valve defect mode types 1, 2, 4 and 6.
Check the cleanliness, condition and fitting of the throttle valve.
Repair if necessary.
If the fault is still present, manually check that the throttle valve rotates correctly.
Repair if necessary.
If the fault is still present, manipulate the harness in order to note a change in fault status (present  stored).
Look for possible damage to the wiring harness, check the condition and the connection of the connectors of the
injection computer and motorised throttle valve.
Repair if necessary.
