U059E Ford Code - Invalid Data Received From NOX Sensor 'A'
Quick Answer
The U059E diagnostic trouble code for Ford vehicles indicates that the Engine Control Module (ECM) has detected invalid data being received from the NOx (Nitrogen Oxide) sensor 'A'. Common causes include Faulty NOx Sensor: The most common cause of this code is a malfunctioning or failed NOx sensor, Wiring Issues: Corrosion, damage, or poor connections in the wiring harness between the sensor and ECM can cause communication errors, ECM Malfunction: A problem with the Engine Control Module itself can also lead to invalid data being received from the NOx sensor. 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 U059E Ford Description
The U059E diagnostic trouble code for Ford vehicles indicates that the Engine Control Module (ECM) has detected invalid data being received from the NOx (Nitrogen Oxide) sensor 'A'. The NOx sensor is responsible for monitoring the levels of nitrogen oxide in the vehicle's exhaust gases to ensure compliance with emissions regulations. When the ECM detects invalid data from this sensor, it can lead to issues with the vehicle's emissions control system, potentially causing the engine to run inefficiently and producing higher levels of harmful emissions.
Common Causes of U059E Ford
- Faulty NOx Sensor: The most common cause of this code is a malfunctioning or failed NOx sensor.
- Wiring Issues: Corrosion, damage, or poor connections in the wiring harness between the sensor and ECM can cause communication errors.
- ECM Malfunction: A problem with the Engine Control Module itself can also lead to invalid data being received from the NOx sensor.
- Exhaust System Leaks: Any leaks in the exhaust system before the NOx sensor can affect its readings and trigger this code.
Symptoms of U059E Ford
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Decreased Fuel Efficiency: Invalid data from the NOx sensor can lead to poor fuel efficiency as the engine may not be operating optimally.
- Rough Idle: The engine may experience rough idling or hesitation when accelerating due to incorrect data being received from the sensor.
- Failed Emissions Test: If the NOx sensor is not functioning properly, the vehicle may fail emissions tests due to increased nitrogen oxide emissions.
How to Fix U059E Ford
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific error codes and pinpoint the cause of the problem.
- Inspect Wiring: Check the wiring harness for any signs of damage, corrosion, or poor connections. Repair or replace as necessary.
- Replace NOx Sensor: If the sensor is found to be faulty, replace it with a new one to restore proper functionality.
- Clear Codes: Once the repair is complete, clear the error codes from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
- Perform Emissions Test: After repairing the NOx sensor issue, it's advisable to have the vehicle undergo an emissions test to ensure it meets regulatory standards.
Cost to Fix U059E Ford
The cost of repairing the U059E code for an invalid data received from the NOx sensor 'A' can vary depending on the specific cause of the issue. On average, the cost of replacing a NOx sensor can range from $200 to $500, including parts and labor. Additional costs may apply if wiring repairs or ECM diagnostics are needed. It's recommended to consult with a qualified mechanic or dealership to get an accurate estimate based on your vehicle's make and model.
