Acceleration Control

Acceleration Control:

2.5L and 3.0L vehicles
The accelerator pedal demand sensor provides an analogue voltage to the PCM which is proportional to the accelerator pedal position. A throttle position sensor provides a signal to the PCM which monitors throttle plate position.

After receiving these signals and monitoring the wheel speed signal output, coolant temperature, rotary switch status (automatic transmission) and inertia switch confirmation, the PCM then issues a throttle request signal. A motor within the throttle body rotates the throttle plate to a position which is relative to the position demanded.
