Accelerator Position System (Aps) - Ducati MONSTER 821 Workshop Manual

Accelerator Position System (APS)

The Acceleration Position Sensor (APS) (1) or throttle twistgrip sensor, is a potentiometer that generates an
electric input sent to the control unit which receives information on:
- throttle twistgrip position;
- activation dynamics.
This input allows acting on the ride-by-wire system to obtain a better and smoother power supply, directly
"corrected" by the control unit.
To remove the APS, follow the instructions in chapter "Removing the throttle
control".
APS connector (2) to the wiring.
To check the APS correct operation, connect the DDS 2 diagnosis instrument to the control unit diagnostic
socket (A), located on the rear subframe, on the left side; remove the seat to reach it.
