DESCRIPTION AND OPERATION
ACCELERATION CONTROL
The acceleration control consists of one of the following:
A fixed accelerator pedal and position sensor assembly
An adjustable accelerator pedal and position sensor assembly
The throttle is controlled by an accelerator pedal position (APP) sensor on the accelerator pedal assembly. The
APP sensor sends a signal to the PCM in response to throttle pedal movements initiated by the driver. The PCM
sends a signal to the electronic throttle control which increases and decreases throttle position.
Some vehicles are equipped with adjustable pedals. This allows both the accelerator and brake pedals to be
adjusted simultaneously forward or rearward. A rocker switch on the instrument panel provides adjustment on
the pedal assembly when it is activated. On vehicles with the memory seat option, the pedal position can be
controlled by the memory selection, as well as the rocker switch. The adjustable accelerator pedal can be
serviced separately from the adjuster. The components in the acceleration control system are not adjustable and
new components must be installed if damaged or worn.
