P2285: Ford 6.0L ICP sensor voltage is below range
Ford's documented P2285 check detects an injection-control pressure sensor input below 0.03 volt.

Documented application
Ford 2004 model-year 6.0L diesel OBD summary, revision August 7, 2003; the cited monitor and transmission implementation only.
The code alone does not identify a failed part or establish that a vehicle is safe to drive. Confirm the vehicle, reporting module and applicable service procedure.
P2285 is injection-control pressure sensor circuit low in Ford's 2004 6.0L diesel summary. Its stated threshold is signal voltage below 0.03 volt. The low condition refers to the electrical input, not necessarily low hydraulic injection-control pressure.
Electrical validity comes before pressure interpretation
The monitor runs continuously in an eight-millisecond task, with a typical duration below one second and no listed entry conditions. Ford separately uses P2290 for actual pressure falling below command during running. A signal outside its electrical range and a valid pressure measurement that misses its target are different diagnostic facts.
The companion P2286 marks the high electrical boundary. These circuit checks help determine whether the pressure information can be trusted before a functional pressure-control fault is investigated.
Avoid replacing hydraulic parts from a signal code
Preserve the raw ICP signal information and accompanying pressure codes. Use the exact engine's sensor-circuit procedure to isolate the signal path, sensor and controller input before interpreting displayed pressure as a physical measurement. The source supplies no hydraulic repair verdict or safe pressure-release method. High-pressure injection-control testing belongs within the specified professional procedure, not an improvised test at a fitting.
Source and applicability
Ford 2004 model-year 6.0L diesel OBD summary, revision August 7, 2003; the cited monitor and transmission implementation only. Ford source, physical PDF pages 23, 24. The documented monitor explains the fault decision; vehicle-specific service information is still needed for connector identification and a complete repair procedure.
