Pinpoint Tests RI: REDUCTANT 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:
- reductant temperature sensor
- reductant pump assembly
- harness circuits: RDT and SIGRTN
- reductant dosage control module (5H298)
- PCM (12A650)
