Accelerator Position Sensor (Throttle Grip) - Ducati Diavel Workshop Manual

Introduction to the engine control system
If none of the aforementioned tests identify the problem and the engine speed sensor is in proper working order, replace
the engine control unit.
Component replacement methods
No special measures are necessary in order to replace the engine speed-timing sensor. Check the air gap between the
sensor and one of the teeth of the phonic wheel, inserting a feeler gauge through the hole on the left hand crankcase half
(covered by a cap). The air gap must measure 0.6 mm +/- 0.3 mm and is non-adjustable.

Accelerator position sensor (throttle grip)

Introduction
An accelerator position sensor (APS) is mounted on the throttle body of the Diavel, which measures the degree of aperture
of the throttle grip.
- The throttle grip is connected to the sensor via two metal cables.
- The sensor transmits information to the ECU relative to the "torque demand" made by the rider by twisting the throttle
grip.
- For safety reasons, the sensor contains two potentiometers (a main potentiometer – MAIN – and a secondary
potentiometer – SUB) with independent 5V power and ground.
Component assembling position
The accelerator position sensor is mounted on the throttle body and is held in place by two screws.
