PINPOINT TEST RI: Reductant Temperature Sensor: Introduction

2014 Ford F-450 Super Duty Platinum, 4WDSECTION 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 temperature sensor
  • harness circuits: RDT and RDLRTN
  • powertrain control module (PCM) (12A650)
