AP (Accelerator Pedal Position)
• The AP (Accelerator Pedal) is a three track pedal. The
AP incorporates three potentiometers. Throughout the
movement of the AP the resistance values of the three
potentiometers must agree. During the movement of
the AP if any 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 ECM will allow the engine
to idle only and illuminate the check engine light.
• Having three (3) signals for comparison
is an added safety feature.
