Pinpoint Tests X: Exhaust Pressure (EP) 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:

harness circuits: EP, SIGRTN, VREF
EP sensor (9J460)
PCM (12A650)
