ICC 000110.04 – Engine Coolant Temperature Voltage Below Normal, or Shorted to Low Source

ICC 000110.04 (ICC 110.04)

Code: 000110.04

Shortcode: 110.04


This error indicates that the coolant temperature sensor has a short circuit or is grounded, resulting in a voltage below the normal operating range. This could be due to a wiring issue, a defective sensor, or a grounding problem.


The engine control module (ECM) may not receive accurate temperature readings, potentially leading to improper engine operation and triggering a warning light on the dashboard.


  • Inspect Wiring and Connections:
    • Check the sensor wiring for any signs of damage or shorts.
    • Ensure all connectors are secure and free from corrosion.
  • Test the Coolant Temperature Sensor:
    • Use a multimeter to check the sensor’s resistance and compare it to the manufacturer’s specifications.
    • Replace the sensor if it is out of range or defective.
  • Check for Proper Grounding:
    • Ensure the sensor’s grounding is intact and not causing a short.
    • Repair any grounding issues detected.


Regular inspection of sensor wiring and connections can help prevent electrical issues that trigger this code.
