Pinpoint Test AG: Accelerator Pedal Position (APP) Sensor: Introduction

WARNING: This page is about a different variant/trim than selected.

NOTE: After clearing an APP sensor 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.

NOTE: Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.

This pinpoint test is intended to diagnose the following:

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