Pinpoint Tests WA: Exhaust Gas RECIRCULATION Temperature (EGRT) Sensor: Introduction

WARNING: This page is about a different car, the 2020 Ford F-550 Super Duty, 2020 Ford F-450 Super Duty, 2020 Ford F-350 Super Duty, 2020 Ford F-250 Super Duty, and 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

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
PCM (12A650)
