U110B RAM Code - Lost Engine Coolant Message
Quick Answer
The U110B diagnostic trouble code (DTC) specifically refers to a "Lost Engine Coolant Message" in the vehicle's onboard computer system. Common causes include Faulty Coolant Temperature Sensor: The most common cause of the U110B code is a malfunctioning or failed coolant temperature sensor, Wiring Issues: Corrosion, damage, or poor connectivity in the wiring harness between the sensor and the ECM can prevent the signal from reaching the ECM, ECM Malfunction: A faulty engine control module may not be able to receive or interpret the coolant temperature sensor signal correctly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U110B RAM Description
The U110B diagnostic trouble code (DTC) specifically refers to a "Lost Engine Coolant Message" in the vehicle's onboard computer system. This code indicates that the engine control module (ECM) has not received a signal from the coolant temperature sensor, which is responsible for monitoring the temperature of the engine coolant. The coolant temperature sensor plays a crucial role in ensuring that the engine operates within the optimal temperature range for performance and efficiency.
Common Causes of U110B RAM
- Faulty Coolant Temperature Sensor: The most common cause of the U110B code is a malfunctioning or failed coolant temperature sensor.
- Wiring Issues: Corrosion, damage, or poor connectivity in the wiring harness between the sensor and the ECM can prevent the signal from reaching the ECM.
- ECM Malfunction: A faulty engine control module may not be able to receive or interpret the coolant temperature sensor signal correctly.
- Coolant Leaks: Low coolant levels due to leaks can also trigger the U110B code by affecting the sensor's readings.
Symptoms of U110B RAM
- Check Engine Light: The most common symptom associated with the U110B code is the illumination of the check engine light on the vehicle's dashboard.
- Engine Overheating: Without accurate coolant temperature data, the engine may overheat, leading to potential damage and reduced performance.
- Poor Fuel Efficiency: A malfunctioning coolant temperature sensor can cause the engine to run inefficiently, resulting in decreased fuel economy.
- Rough Idle or Stalling: Inaccurate coolant temperature readings can affect engine performance, leading to rough idling or stalling issues.
How to Fix U110B RAM
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific DTC and pinpoint the exact cause of the lost engine coolant message.
- Inspect Coolant Temperature Sensor: Check the coolant temperature sensor for any signs of damage or malfunction and replace if necessary.
- Check Wiring and Connections: Inspect the wiring harness for any corrosion, damage, or loose connections, and repair or replace as needed.
- Test ECM Functionality: Verify that the engine control module is functioning correctly by testing its ability to receive and interpret signals from the coolant temperature sensor.
- Clear Codes and Test Drive: After completing the repairs, clear the DTC from the ECM memory, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix U110B RAM
