Pinpoint Test ME: Fuel Pump Control: Introduction

WARNING: CONTACT WITH EXPOSED FUEL INJECTOR WIRING, IF ENERGIZED, MAY RESULT IN ELECTRIC SHOCK. USE CARE WHEN WORKING ON OR AROUND ENERGIZED FUEL INJECTOR WIRING. FUEL INJECTOR WIRING SUPPLIES HIGH VOLTAGE TO OPERATE THE FUEL INJECTORS. FAILURE TO FOLLOW THIS INSTRUCTION MAY RESULT IN SERIOUS PERSONAL INJURY.

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: FPCV, FVCV, and VPWR
fuel volume control valve (9J307)
fuel pressure control valve (9C968)
