Pinpoint Tests RF: Reductant Pressure Sensor: Introduction

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:

reductant pressure sensor
harness circuits: RDP, VREF, and SIGRTN
powertrain control module (PCM) (12A650)
