The most common cause of U0C25 is a faulty steering angle sensor, with an average repair cost of $150 to $300. Wiring issues and software glitches also contribute, with costs varying based on the complexity of repairs.
Can I drive my car with U0C25 or should I stop immediately?
It is not advisable to drive your vehicle with a U0C25 code. The loss of steering assist can create dangerous driving conditions, especially in tight spaces or during sudden maneuvers.
How can I diagnose U0C25 myself using GeekOBD APP?
You can use the GeekOBD APP to scan for DTCs and view freeze frame data. Start with a visual inspection and then check the steering angle sensor readings to ensure they are within specification.
What vehicles are most commonly affected by U0C25?
DTC U0C25 is commonly seen in 2016-2019 Ford models such as the Fusion and Escape, where the steering angle sensor may suffer from wear or faults.
How can I prevent U0C25 from happening again?
Regular maintenance checks, including inspections of the steering system and timely software updates, can help prevent issues that may lead to DTC U0C25.
What is U0C25?
The diagnostic trouble code (DTC) U0C25 indicates a problem with the Electric Power Steering (EPS) Assist system, specifically related to the steering angle sensor. This code is commonly found in vehicles like the 2016-2019 Ford Fusion and the 2017-2019 Ford Escape. When the EPS system detects a fault, it can lead to reduced steering assist, making it difficult for drivers to maneuver the vehicle effectively. In many cases, a malfunctioning steering angle sensor or wiring issue can trigger this code. Drivers might experience symptoms such as a heavy steering feel or an illuminated warning light on the dashboard. If left unresolved, the problem could lead to unsafe driving conditions, especially at low speeds or during tight turns. It’s crucial to address this issue promptly to ensure safe vehicle operation. Repairing the EPS system may involve replacing the steering angle sensor, checking connections, or recalibrating the system, which can vary in cost and complexity depending on the specific vehicle model and the nature of the underlying issue. Regular maintenance and early diagnosis are vital to preventing such faults from affecting your vehicle’s performance.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0C25 is present:
- Check engine light illuminates, indicating a fault in the steering assist system.
- Heavy steering feel, particularly noticeable during low-speed maneuvers or parking.
- Intermittent loss of power steering assist, making steering difficult and less responsive.
- Steering feels unresponsive or sluggish, especially when turning the wheel.
- Possible noise coming from the steering column or associated components when turning.
Possible Causes
Most common causes of U0C25 (ordered by frequency):
- Faulty steering angle sensor (60% likelihood) - This sensor detects the angle of the steering wheel and can fail due to wear over time.
- Wiring issues (25% likelihood) - Damaged or corroded wiring can disrupt the signal between the sensor and the EPS control module.
- Software glitches (10% likelihood) - Occasionally, the EPS system may require a software update or recalibration to function correctly.
- Power steering control module failure (3% likelihood) - A less common cause that can lead to a complete loss of steering assist.
- Mechanical issues in the steering system (2% likelihood) - Problems such as low power steering fluid or a failing pump could also contribute.
