Pinpoint Tests FB: Charge Air Cooler Temperature (CACT) 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:

harness circuits: CACT and SIGRTN
CACT sensor (12A697)
PCM (12A650)
