PINPOINT TEST DK: Accelerator Pedal Position (APP) Sensor: Introduction

NOTE: After clearing an APP sensor diagnostic trouble code (DTC) to verify a repair or an intermittent concern, apply the accelerator pedal before carrying out the self-test. Take 10 seconds to carry out a full sweep of the accelerator pedal from fully released to fully applied and back to fully released

This pinpoint test is intended to diagnose the following:

APP sensor (9F836)
harness circuits: APP1, APP2, APPRTN1, APPRTN2, APPVREF1, APPVREF2, VPWR and GND
PCM (12A650)
