Description:

ECU 000110.04 signals that the engine coolant temperature sensor’s input voltage has dropped below the specified minimum, suggesting a short to ground. This fault typically results in lower than actual temperature readings being reported to the ECU.

Reaction:

Inaccurate low readings may prevent the ECU from implementing necessary cooling measures, risking overheating.

Recommendations:

• Check Sensor and Circuit Integrity: Inspect the sensor and its circuitry for any signs of grounding or wire damage.
• Test Voltage Levels: Verify the sensor’s voltage using diagnostic tools to ensure it aligns with the specified requirements.
• Rectify Electrical Issues: Replace or repair any faulty components that may be causing the voltage drop.
• ECU System Reset: After the issue is resolved, reset the ECU to ensure it correctly processes the corrected signals.

Note:

Regular electrical maintenance will help ensure the longevity and reliability of sensor operations, preventing malfunctions due to improper voltage levels.
