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: APPRTN, APPRTN2, APPVREF, APPVREF2, APP, APP2, and APP3
powertrain control module (PCM) (12A650)
