What is U0472?

DTC U0472 is a diagnostic trouble code that indicates a communication issue between the vehicle's control modules, specifically related to the Steering Angle Sensor. This code is commonly triggered when the powertrain control module (PCM) is unable to communicate with the steering angle sensor module. In simpler terms, it means that your vehicle is having trouble understanding the position of the steering wheel in relation to the car’s movement. This can affect features such as stability control, traction control, and even the responsiveness of your steering. If ignored, it can lead to handling issues or even safety concerns during driving. For car owners, this means that the check engine light will likely illuminate, and various stability-related systems may not function correctly, causing potential safety risks. Therefore, it's crucial to address this code promptly to ensure your vehicle operates safely and effectively.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0472 is present:

  • The check engine light remains on, indicating an underlying issue that requires attention.
  • Loss of stability control features can be felt, especially during sharp turns or slippery conditions.
  • The steering may feel unresponsive or erratic, causing discomfort while driving.
  • Unexpected activation of traction control, which can lead to stalling in certain driving conditions.
  • Increased fuel consumption as the vehicle's systems struggle to maintain optimal performance.

Possible Causes

Most common causes of U0472 (ordered by frequency):

  1. The most common cause of U0472 is a defective steering angle sensor, which accounts for about 60% of cases. If the sensor is faulty, it may not relay accurate information to the PCM, disrupting communication.
  2. Wiring issues or loose connections can also lead to this code, responsible for roughly 20% of occurrences. Corrosion or damage to the wiring harness can interrupt the signal.
  3. Software glitches in the vehicle’s control modules can create a communication failure, making up about 10% of the cases. Keeping your software updated can prevent this.
  4. Less commonly, failure in the PCM itself can trigger this code, which is a more serious issue requiring significant repairs.
  5. In rare situations, external factors, such as aftermarket modifications or accessories interfering with the vehicle's electronics, can provoke this error code.
