Pinpoint Test WA: Exhaust Gas Recirculation Temperature (EGRT) Sensor: Introduction
WARNING: This page is about a different variant/trim than selected.
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)
