It’s advisable to stop driving immediately if you experience heavy steering or loss of power steering. This can lead to dangerous driving conditions.
How can I diagnose U0F07 myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for codes, retrieve freeze frame data, and monitor live sensor data to pinpoint the issue in the EPS system.
What vehicles are most commonly affected by U0F07?
The U0F07 code is frequently reported in 2013-2018 Ford Fusion models, as well as some other Ford vehicles equipped with electronic power steering.
How can I prevent U0F07 from happening again?
Regular maintenance of your vehicle's electrical system, including battery checks and ensuring connections are secure, can help prevent future occurrences of this code.
What is U0F07?
The U0F07 diagnostic trouble code indicates a communication issue within the electric power steering (EPS) system of your vehicle. This code typically arises when there is a fault in the communication between the EPS control module and other vehicle systems, such as the engine control module (ECM) or the body control module (BCM). In practical terms, this means that the EPS system may not be functioning optimally, leading to a heavy steering feel, or, in some cases, complete loss of power steering assistance. Drivers may notice that steering the vehicle becomes increasingly difficult, especially at lower speeds or during tight maneuvers. Ignoring this issue can lead to more severe steering problems or even potential safety risks while driving. It's essential to address the U0F07 code promptly to ensure your vehicle maintains optimal handling characteristics and safety on the road.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0F07 is present:
- The check engine light may illuminate, signaling an underlying issue with the EPS system.
- Drivers may experience a heavy steering feel, especially at low speeds, making maneuvering difficult.
- An abrupt loss of power steering assistance while driving, which can be alarming and challenging to manage.
- Unusual noises coming from the steering column, such as whining or grinding sounds, indicating potential mechanical issues.
- Intermittent power steering assistance that fluctuates while driving, leading to inconsistent handling.
Possible Causes
Most common causes of U0F07 (ordered by frequency):
- The most common cause of the U0F07 code is a faulty EPS control module, accounting for approximately 40% of cases. This module is responsible for translating inputs from the steering wheel into signals that assist in steering the vehicle.
- Another frequent cause is damaged wiring or connectors within the EPS system, which can disrupt communication between various modules. Checking for loose or corroded connections is crucial.
- Electrical interference or issues within the vehicle's network can also trigger this code. Ensuring that the vehicle's battery and charging system are functioning correctly can help prevent this.
- Less common but serious causes include software glitches within the EPS control unit, which may require a software update from a dealership to rectify.
- A rare cause could be a malfunctioning steering angle sensor, which can mislead the EPS system into thinking the steering wheel is not in the correct position.
