P2283 is the general circuit code for the injector control pressure (ICP) sensor. ICP describes the high-pressure engine oil that hydraulically actuated unit injectors (HEUI) use to pressurise fuel, as on Navistar-built Ford Power Stroke diesels; the sensor reports rail pressure so the injection pressure regulator can be closed-loop controlled. No manufacturer documents P2283 publicly. Ford's 6.0L summaries for 2003 and 2004 split the electrical check into P2285 (below 0.03 V) and P2286 (above 4.83 V), and Ford's 2014 PCM code table lists those two but not P2283. CARB requires diesel fuel-pressure control, explicitly including hydraulic fluid, to be monitored. Without a valid ICP signal the PCM substitutes a default value, so power and starting suffer.

Likely causes

Failed ICP sensor, often with oil inside the connector
Damaged signal, reference or ground wire of the sensor
5-volt reference circuit pulled down by another sensor

Symptoms

  • Low power and hesitation
  • Hard or long cranking, especially when hot
  • MIL on
