Pinpoint Tests MC: Fuel Temperature 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:
- FRT sensor (9F951)
- fuel pressure and temperature sensor
- harness circuits: FRT and SIGRTN
- PCM (12A650)
