Acceleration Control

Acceleration Control:

The accelerator pedal position sensor provides an analogue voltage to the powertrain control module (PCM) proportional to the accelerator pedal position. A throttle position sensor provides a signal the to PCM to monitor the throttle plate position. After receiving these signals and monitoring the output wheel speed signal, coolant temperature, rotary switch status (automatic transmission) and inertia switch confirmation, the PCM can then issue a throttle request signal. A motor within the throttle body rotates the throttle plate according to the current supplied.
