P2285 on Ford by model: symptoms, diagnosis and fix
The IPR valve on the 6.0L Power Stroke can develop an external oil leak or fail to regulate injection control pressure, causing hard starting, rough idle, and loss of power. The o-ring seal deteriorates over time.
Common Symptoms
- Hard starting
- Oil leak near turbo area
- Low power
- Rough idle
- Long crank times
How to Fix
Replace the IPR valve and o-ring seal. Clean the area thoroughly. Verify injection control pressure returns to normal (500-700 PSI at idle).

Frequently asked questions
What does P2285 mean on a Ford?
P2285 stands for "Injector Control Pressure Sensor Circuit Low." This code means the engine computer detected a low-voltage (or out-of-range low) signal from the injector control pressure (ICP) sensor, used mainly on certain diesel engines with high-pressure oil-actuated fuel injection. This sensor monitors the pressure that operates the injectors. A faulty low signal means the computer can't accurately manage injection pressure, which can cause hard starting, no-start, rough running, stalling, or reduced power. Because it directly affects fueling, it should be diagnosed promptly. On Ford it is documented across 1 model: Excursion.
What are the most common causes of P2285?
The most common causes of P2285 are: Faulty injector control pressure (ICP) sensor, Wiring shorted to ground or open in the sensor circuit, Corroded or oil-contaminated sensor connector, Low or contaminated high-pressure oil supply, Failed high-pressure oil pump (related), PCM/IDM circuit fault (rare). The specific cause varies by vehicle.
How much does it cost to fix P2285 on a Ford?
Published repair estimates on Ford range from $100 to $350 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
