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.
Affected components
- Icp sensor
- High pressure oil pump
- Icp wiring
Common causes
- High likelihood: ICP sensor drift
- Medium likelihood: Leak in high-pressure oil system
- Low likelihood: 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
