Severity

highDrive with caution; the engine may misfire or stall unexpectedly.

Summary

Code P2285 indicates an abnormally low input voltage in the circuits associated with the Injector Control Pressure Sensor (ICP) on diesel engines. This sensor is typically located near the turbocharger and monitors oil pressure to control fuel injection.

Symptoms

  • Illuminated warning light
  • Oil leaks appearing from the turbocharger area
  • No-start condition
  • Difficult starting when hot
  • Engine misfires at certain speeds or loads
  • Poor idling quality with fluctuating idle speed
  • Hesitation and surging during operation
  • Increased fuel consumption
  • Repeated engine stalling

Common Causes

  • Failed, defective, or malfunctioning ICP sensor (most common)
  • Damaged, burnt, shorted, corroded, or disconnected wiring and/or electrical connectors
  • Rarely: Failed or failing PCM

Diagnosis

  1. Inspect and test the ICP sensor for proper operation.
  2. Check wiring and connectors between the sensor and PCM for damage, corrosion, or disconnection.
  3. Verify that the oil pressure is within normal range.
  4. Consider professional assistance due to difficult access to the sensor.

Fixes

  • Replace the faulty ICP sensor

FAQ

Where is the ICP sensor located?
