Injector Control Pressure Sensor Circuit Low
The voltage of the injector control pressure sensor is below the calibrated minimum. The signal indicates either a short to ground or a sensor that has lost its supply.
Affected components
- Icp sensor
- Icp wiring
Common causes
- High likelihood: Signal shorted to ground
- Medium likelihood: Open 5 V supply
- Low likelihood: Connector pins corroded - high contact resistance
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
