P2284 — Injector Control Pressure Sensor Circuit Range/Performance
The injector control pressure (ICP) sensor on HEUI diesel systems reports a value that does not match expected operating range or commanded pressure. Affects fuel injection timing and quantity.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
Affected components
- Icp sensor
- High pressure oil pump
- Icp wiring
Possible causes to check
These are possible checks, not a ranked diagnosis. Follow the vehicle manufacturer's test procedure before replacing parts.
- ICP sensor drift
- Leak in high-pressure oil system
- Sensor element aged beyond calibration window
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
- A drive cycle may be required after repair
- Reduced-power or limp mode may occur
