• 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.
