P1264 FORD Description

The fuel injectors are connected to the high-pressure fuel rail and deliver a calibrated amount of fuel directly into the combustion chamber. The piezo actuator is commanded on by the PCM during the main injection stage for approximately 0-400 microseconds. The fuel injectors on and off time are controlled by the piezo actuator device which allows extreme precision during the injection cycle. The Diagnostic Trouble Code (DTC) is detected by the Fuel Injector Interface Module in the secondary (rearward) fuel injector circuit.
