P2286 means the ICP sensor voltage has risen to the top of the range. In Ford's 2004 summary for the 6.0L Power Stroke the limit is above 4.83 V, checked every 8 ms and confirmed in less than one second; the 2003 edition already names the code alongside P2285. A reading that close to the 5-volt reference typically results from the signal wire touching the reference, a broken sensor ground or a sensor that has failed internally. Ford switches on the MIL for P2286 also on heavy federal trucks above 8,500 lb with their reduced OBD calibration, and its 2014 PCM code table marks the code as a MIL code. The engine runs on an estimated rail pressure until the fault is fixed. P2285 is the low counterpart, P2288 a real over-pressure condition.

Likely causes

Open sensor ground circuit
Signal wire shorted to the 5-volt reference or another voltage
ICP sensor failed with output stuck high

Symptoms

  • MIL on
  • Reduced power and possibly harsh running
