Injector Control Pressure Sensor Circuit High
The voltage of the injector control pressure sensor is above the calibrated maximum. Likely a short to supply voltage or an open ground in the sensor circuit.
Affected components
- Icp sensor
- Icp wiring
Common causes
- High likelihood: Signal shorted to supply
- Medium likelihood: Open ground wire
- 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
