Pinpoint Tests ME: Fuel Pump Control: Introduction

WARNING: USE CARE WHEN WORKING ON OR AROUND ENERGIZED FUEL INJECTOR WIRING. THE FUEL INJECTOR DRIVERS IN THE POWERTRAIN CONTROL MODULE (PCM) SUPPLY HIGH VOLTAGE TO OPERATE THE FUEL INJECTORS. IF ENERGIZED, CONTACT WITH EXPOSED FUEL INJECTOR WIRING CAN RESULT IN ELECTRIC SHOCK. 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:

fuel volume control valve
fuel pressure control valve
harness circuits: FPCV, FVCV, and VPWR
powertrain control module (PCM) (12A650)
