P2285Injector Control Pressure Sensor Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2285 is set when the ICP sensor voltage falls almost to zero. Ford's 6.0L Power Stroke summaries for 2003 and 2004 define it precisely: below 0.03 V, checked every 8 ms without entry conditions, decided in under one second. Such a value cannot come from a working sensor on a 5-volt reference, so it points to an open signal wire, a short to ground, a lost reference voltage or an unplugged sensor. Ford lights the MIL for P2285 even on heavy federal trucks over 8,500 lb that otherwise run a reduced OBD calibration. On a HEUI engine the PCM then has to estimate rail pressure, so starting and response deteriorate. P2286 is the high-voltage counterpart; P2284 covers a valid signal that disagrees with the commanded pressure.
- What you may notice
- MIL on immediately
- Hard starting and reduced power
- Likely causes
- LikelySignal wire open or shorted to ground
- PossibleSensor disconnected or failed internally
- PossibleMissing 5-volt reference supply
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €40 – €400
