WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The purpose of this test is to determine if injector solenoids and valves are operating properly by buzzing all injectors together for about 2 seconds, then each injector will buzz for about one second in numerical order (1-8).
