Test 6: KOEO Injector Electrical Self-Test: Purpose
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.
This test determines if the injector circuits and solenoids are electrically operating without fault. All injectors will first click together for approximately 2 seconds, then each injector will click for approximately 1 second in numerical order (1 through 8). See Fig 1. If a fault is detected, a DTC will be output on the data link at the end of the test when requested by a scan tool. Only a hard fault DTC will be displayed.
