Abstract
In a properly calibrated accelerator pedal sensor that provides a signal representative of pedal position to an electronic control module for the engine, the point at which the associated idle validation switch switches to distinguish idle from non-idle lies within a limited range of positions proximate closed throttle. The invention is a method for performing an in-vehicle test that can quickly determine if the switch point is in or out of calibration. A jumper is inserted between the sensor and the vehicle wiring harness that normally connects to the sensor. The jumper comprises several test points to which a voltmeter can be connected to measure certain voltages during the test and two LED's that are observed during the test. A special slide calculator is used to convert certain test data into a form that can be readily compared with other test data to make the determination regarding the idle validation switch.
