Common Questions

What does U035F mean and how does it affect my car?

The U035F code indicates a communication problem with the steering angle sensor, which is crucial for your vehicle's steering system. If this code appears, you may experience difficulties steering, especially at low speeds. These issues can compromise safety and handling, making it important to address the problem promptly.

What are the most common causes of U035F and how much does it cost to fix?

The most common cause of the U035F code is a faulty steering angle sensor, with repair costs typically ranging from $200 to $350. Other causes include damaged wiring, which may cost between $100 and $250 to fix, and ECU reprogramming, which can be around $150 to $300.

Can I drive my car with U035F or should I stop immediately?

While it's possible to drive a vehicle with the U035F code, it is not recommended, as this code can lead to loss of power steering assist. If you notice any steering difficulties, it's best to stop driving and have the vehicle inspected to prevent accidents.

How can I diagnose U035F myself using GeekOBD APP?

To diagnose the U035F code using GeekOBD APP, start by connecting the app to your vehicle's OBD2 port. Perform a full scan to retrieve all codes and analyze freeze-frame data. Look for any related codes that might give you more context on the issue and check the steering angle sensor's readings for anomalies.

What vehicles are most commonly affected by U035F?

The U035F code frequently affects models such as the Ford F-150 from 2015 to 2019, as well as certain Chevy Silverado models and Dodge Ram trucks from similar years. Always check for recalls or Technical Service Bulletins (TSBs) related to steering issues for your specific model.

How can I prevent U035F from happening again?

To prevent the U035F code from recurring, regularly inspect the electrical connections and wiring related to the steering system for wear or corrosion. Keeping up with scheduled vehicle maintenance and having a professional check your steering system can also help catch issues early.

What is U035F?

The DTC U035F code indicates a communication issue with the vehicle's steering angle sensor. This code is often encountered in vehicles like the Ford F-150 from 2015 to 2019, where the electronic power steering system relies heavily on this sensor for accurate vehicle control. When the U035F code triggers, it generally means that the Engine Control Module (ECM) is unable to communicate with the steering angle sensor, which can lead to a loss of power steering assist. This can create serious handling problems, making the vehicle difficult to steer, especially at low speeds. Drivers may notice an unresponsive steering wheel or may even experience the steering wheel feeling heavier than usual. Ignoring this code can lead to more significant issues down the line, such as complete power steering failure. If you see the U035F code, it’s crucial to address it promptly to ensure safe vehicle operation. In addition to steering problems, you might also experience symptoms like a check engine light, which may stay illuminated until the issue is resolved. Overall, the U035F code signifies a critical fault that requires immediate attention to prevent further complications.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U035F is present:

  • The check engine light may illuminate continuously, indicating a fault in the steering system.
  • Drivers may feel that the steering wheel is heavier than normal, especially during low-speed maneuvers.
  • You might notice a delay in steering response when turning the vehicle, potentially compromising safety.
  • There may be unusual noises coming from the steering column when the steering wheel is turned.
  • In more severe cases, the vehicle could enter a limp mode where steering assist is significantly reduced.

Possible Causes

Most common causes of U035F (ordered by frequency):

  1. The most common cause of the U035F code is a faulty steering angle sensor, with a likelihood of about 60%. This sensor may fail due to wear and tear or electrical issues.
  2. Another cause could be damaged wiring or connectors related to the steering system, often resulting from corrosion or physical damage, accounting for approximately 25% of cases.
  3. Poor connections or loose wiring can also lead to this code, and preventative measures include regular inspections of wiring harnesses and connectors.
  4. Less common, but serious, is a failing Electronic Control Unit (ECU) that struggles to communicate properly, which could cause a complete failure of the steering system.
  5. A rare cause could be software issues within the vehicle's onboard computer, which may require reprogramming or an update.
