Pinpoint Tests RF: REDUCTANT Pressure 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 PRESSURE SENSOR
HARNESS CIRCUITS: RDP, VREF, AND SIGRTN
