PINPOINT TEST P: Misfire/Injector Driver Circuit Operation: Introduction
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Ford RV Cutaway, 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Inspect the fuel injector control module (FICM) harness for damage, chafing and correct routing within the engine compartment and around engine components.
This pinpoint test is intended to diagnose the following:
- fuel injector
- harness circuits: fuel injector close coil, power and ground and fuel injector open coil, power and ground
- FICM (12B559)
- powertrain control module (PCM)
