Electronic Throttle Control Components
Item
1 Accelerator Position Sensor (APS)
2 Accelerator Pedal Assembly
•
Electronic throttle control is in use on vehicles other than
Electric Ranger.
•
On the Electric Ranger, electronic throttle control replaces the
cable between the accelerator pedal and the powertrain.
•
Instead of a mechanical request for power, electronic throttle
control uses electrical signals.
•
The sensing component of electronic throttle control is an
accelerator position sensor (APS) mounted to the accelerator
pedal assembly.
– Three potentiometers in the APS sense the position of the
accelerator pedal.
– The APS sends signals to the TIM, which commands the
motor/transaxle to respond accordingly.
