P1209 · FordInjector Control Pressure System Fault

P1209 on Ford vehicles means the powertrain control module has detected a fault in the injector control pressure system, which on Ford diesels is the high-pressure oil circuit that fires the fuel injectors. The computer compares commanded injector control pressure against the actual pressure reported by the injector control pressure sensor and sets the code when the two disagree beyond a calibrated threshold.
