P0264 on Ford
Cylinder 2 Injector Circuit Low
P0264 on Ford vehicles indicates cylinder 2 injector circuit low. Au7o has documented this code across 1 Ford model — most commonly on F-350. The PCM detected low voltage (short to ground or open on the power side) in the cylinder 2 fuel injector control circuit, preventing proper injector operation and causing a misfire. Typical repair costs on Ford range from $350 to $1,100, depending on the specific model and root cause.
Common Causes of P0264
- •Short to ground in cylinder 2 injector wiring
- •Open on the injector power feed
- •Faulty cylinder 2 injector
- •Loose or corroded connector
- •PCM injector driver fault
P0264 on Ford by Model
Ford F-350(1 issue)
- 6.0L FICM (Fuel Injection Control Module) Voltage Decay Causing Hard Start and Misfire2003-2007
The 6.0L Power Stroke's Fuel Injection Control Module sits on top of the driver-side valve cover and must deliver a 48-volt pulse to fire each HEUI injector. The module is heat-soaked in that location and its internal power supply degrades over time; it is also killed outright by weak batteries or a failing charging system, because the boost circuit is damaged when supply voltage sags below about 12.6 volts during cranking. As FICM main power output drops below roughly 46 volts, the injector solenoids begin to open late, producing hard starting, rough cold running and white smoke. A dying FICM can subsequently damage injectors. F-350s with two batteries that are not replaced as a matched pair are the classic case.
