Removal/refitting

REMOVAL/REFITTING

• Make sure the ignition key is at "STOP" and disconnect the (-) battery terminal.
• Loosen the screws and remove the left engine compartment guard.

1. Loosen the clips and remove the corrugated sleeve with resonators after releasing the intermediate resonator from the fastening pin.

1. Disconnect the cam angle sensor electrical connection.
2. Loosen the fastening screw and remove the cam angle sensor with electrical wiring.

ACCELERATOR PEDAL POTENTIOMETER

The accelerator pedal is fitted with two built-in potentiometers:

• one main potentiometer
• one back up potentiometer.

The injection ECU performs the following recovery strategies:

• - if one of the two potentiometers fails, the throttle is opened to a maximum of 40° over a long time
• - if both potentiometers fail completely the throttle is closed.

The accelerator pedal is adjusted by excluding the respective stop (which should not exceed the notch).

Operation

The sensor consists of a casing (1) fastened to the pedal board by means of a flange inside which a shaft (2) is axially connected to the double track potentiometer (3). A helicoid spring on the shaft ensures the correct pressure resistance while a second spring ensures return when released. Operative field from 0° to 70°; mechanical stop at 88°.

REMOVAL/REFITTING

• Make sure the ignition key is at "STOP" and disconnect the (-) battery terminal.
• Remove the valve guard (see Assembly 70).
