STOREDACCELERATOR PEDAL POSITION SIGNAL
1.DEF: Signal incoherent
NOTESConditions for applying the fault finding procedure to stored faults:
If the customer complains of intermittent faults typical of defect mode type 3
(no accelerator pedal, cruise control or speed limiter), and that the ESP indicator
light comes on but the injection system displays no present faults, apply this fault
finding procedure.
Special notes:
This fault finding procedure enables an accelerator pedal mechanical seizure type fault
to be displayed whilst the pedal is depressed (when the driver's foot is lifted, the pedal
position remains the same). In this case, the driver will brake.
This program enables an inconsistency in the driver's behaviour, such as the brake
pedal and accelerator being depressed simultaneously to be detected (but enables
heel/toe points and left foot braking to be performed without displaying a fault).
There are two possible cases:
1. The fault finding procedure detects constant acceleration then braking with the
acceleration still maintained => change to reversible type 3 defect mode (see
System operation) which no longer recognises the accelerator pedal => warning
light does not come on, fault is not stored. If the accelerator pedal changes position
before the end of a time delay (approximately 31 seconds), it exits defect mode
and returns to normal mode.
2. If the accelerator pedal does not change position for the entire time delay
(approximately 31 seconds), it goes irreversibly into defect mode (requires the
ignition to be switched off to exit it). The warning light comes on and the fault is
stored. This fault finding procedure has no relation with the throttle position.
An accelerator fault (locking, for example) is needed to show the stored fault.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.

CLIO III or MODUS, component code 120).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If the fault is still present, check (with the ignition on) for + 12 V on connection 3FB of the controlled coolant
thermostat.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
