AP (Accelerator Pedal
Position)
• The AP (Accelerator Pedal) is a
three track pedal. The AP
incorporates three potentiometers.
Through out the movement of the
AP the resistance values of the
three potentiometers must agree.
During the movement of the AP if
one of the three potentiometer
readings do not agree, the check
engine light will illuminate and the
vehicle will continue to perform as
normal. If two signals from the AP
are lost the PCM will allow the
engine to idle only and illuminate
the check engine light.

• The three-track pedal is a safety
feature. The three track pedal takes
the place of the Idle Validation
Switch allowing for limited system
failure and still maintaining
performance.
