Accelerator Pedal - Toro Workman GTX Electric & Lithium Service Manual

Accelerator Pedal

The accelerator pedal is attached to the foot board un-
der the dash (Fig. 43). This pedal is used as one of the
inputs for the vehicle controller to determine vehicle
speed. The electronic control incorporated in the accel-
erator pedal is a non--contact, rotary hall effect sensor
that varies output voltage based on the pedal position.
When the operator presses or releases the accelerator
pedal, the voltage from the pedal sensor changes. Out-
put voltage from the pedal is used by the controller to de-
termine appropriate current flow to the traction motor.
If the accelerator pedal is thought to be faulty, consider
the following before replacing the pedal:
1. Make sure that the accelerator pedal moves smooth-
ly through its entire range of motion.
2. Check the vehicle controller for any existing faults
that indicate a problem with the accelerator pedal (see
Controller in this section of this chapter).
3. The wire harness connector and accelerator pedal
connector should be inspected for corrosion or connec-
tor pin damage.
NOTE: No internal parts are available for the accelera-
tion pedal.
