When it comes to diagnosing and repairing Ford vehicles, the Ford U059E Code can be an intimidating issue. This code is a diagnostic trouble code indicating an issue with the controller area network (CAN) communication with the nitrogen oxide (NOx) module. The powertrain control module (PCM) monitors the CAN for messages from the NOx module. When the PCM does not receive the message from the NOx module within the specified amount of time, the DTC U059E is set and a Check Engine Light is illuminated on the dashboard. Understanding the underlying causes and solutions to this diagnostic trouble code can help to repair the issue and get the vehicle back on the road.
Causes and Solutions for Ford U059E Code
| Causes | Solutions |
|---|---|
| NOx Sensor A Failure | Replace the NOx sensor |
| Defective PCM | Replace the PCM |
| Faulty Wiring or Connections | Repair any faulty wiring or connections |
| Defective CAN Bus | Replace the CAN Bus |
NOx Sensor A Failure
The Ford U059E Code is often caused by a failure in the NOx Sensor A. When the NOx Sensor A is not working correctly, the PCM cannot properly communicate with the NOx Module and the DTC U059E will be set. To repair this issue, the NOx Sensor A must be replaced.
Defective PCM
Another possible cause of the Ford U059E Code is a defective PCM. When the PCM is defective, it may not be able to properly communicate with the NOx Module and the DTC U059E will be set. If this is the case, the PCM must be replaced to resolve the issue.
Faulty Wiring or Connections
Faulty wiring or connections can also be the cause of the Ford U059E Code. When the wiring or connections are damaged or faulty, the PCM is unable to communicate properly with the NOx Module and the DTC U059E will be set. To repair this issue, any faulty wiring or connections must be repaired.
Defective CAN Bus
The final cause of the Ford U059E Code is a defective CAN Bus. The CAN Bus is the communication system for the PCM, and when it is not working properly, the PCM cannot communicate with the NOx Module and the DTC U059E will be set. To repair this issue, the CAN Bus must be replaced.
Conclusion
The Ford U059E Code can be an intimidating issue to diagnose and repair. However, understanding the underlying causes and solutions can help to repair the issue and get the vehicle back on the road. Understanding the Ford U059E Code is key to properly diagnosing and repairing Ford vehicles.
