Pinpoint Test AZ: Exhaust Gas Recirculation (EGR) Cooler System: 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: EGRCBV and VPWR
EGR cooler (9F464) (9V466)
PCM (12A650)
