II. Throttle Pedal sensor :
Component Details :
This sensor is secured to the accelerator pedal
inside it contains an axially-located shaft
connected to two potentiometers: a main one and
one safety one.
A coil spring on the shaft ensures the correct
amount of resistance to pressure while a second
spring ensures return following release.
The redundant signal reading makes it possible to
continuously monitor the plausibility of the
readings in order to guarantee complete safety
whilst driving even if there is a failure.
The accelerator pedal position is converted into
an electrical voltage signal and sent to the EMS
ECU by the potentiometer connected to the pedal.
The accelerator pedal position signal is processed
together with the information relating to the engine
rpm to produce the desired torque and engine
speed.
