Pinpoint Tests WA: Exhaust Gas Recirculation Temperature (EGRT) 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: EGRT11, EGRT12, and SIGRTN
EGRT11 and EGRT12 sensors
