U010E Code - Lost Communication With Reductant Sensor Module
Quick Answer
The U010E diagnostic trouble code indicates that the vehicle's engine control module (ECM) has lost communication with the reductant sensor module. Common causes include Faulty reductant sensor module, Wiring or connection issues between the ECM and reductant sensor module, Corrosion or damage to the electrical connectors. 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 U010E Description
The U010E diagnostic trouble code indicates that the vehicle's engine control module (ECM) has lost communication with the reductant sensor module. The reductant sensor module is responsible for monitoring the levels of diesel exhaust fluid (DEF) in the vehicle's selective catalytic reduction (SCR) system. This system is crucial for reducing harmful emissions and ensuring the vehicle meets emissions standards.
Common Causes of U010E
- Faulty reductant sensor module
- Wiring or connection issues between the ECM and reductant sensor module
- Corrosion or damage to the electrical connectors
- ECM software issues
- Environmental factors such as extreme temperatures affecting sensor performance
Symptoms of U010E
- Check Engine Light illuminated
- Reduced engine performance
- Increased fuel consumption
- Failed emissions test
- Poor acceleration
How to Fix U010E
- Perform a diagnostic scan to confirm the U010E code and identify the specific cause.
- Inspect wiring and connectors for damage or corrosion, repairing or replacing as needed.
- Test the reductant sensor module for proper functionality and replace if faulty.
- Update ECM software if necessary to ensure proper communication.
- Clear the code and perform a test drive to verify that the issue has been resolved.
Cost to Fix U010E
The typical repair costs for addressing a U010E code can vary depending on the specific cause of the issue. Parts such as a new reductant sensor module can range from $100 to $300, while labor costs can range from $100 to $300. Overall, the total repair cost could range from $200 to $600. However, it's important to note that these are rough estimates and actual costs may vary based on factors such as location, vehicle make and model, and labor rates at the auto repair shop.
