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
Description:
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.
Reaction:
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.
Recommendations:
- 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.
Note:
Regular inspection of sensor wiring and connections can help prevent electrical issues that trigger this code.
