What is B074C?

DTC B074C indicates a problem within the vehicle's power steering control module, specifically relating to the steering angle sensor. This code is commonly found in various makes and models, particularly in vehicles like the 2016-2020 Ford Fusion and 2017-2020 Honda Accord. When B074C triggers, it typically signifies that the steering angle sensor is malfunctioning or has lost communication with the vehicle's control module. This can lead to issues such as erratic steering behavior, difficulty in steering response, and in some cases, the vehicle may enter a failsafe mode where steering assistance is reduced. Ignoring this code can lead to increased wear on steering components and ultimately a complete steering failure, posing a serious safety risk on the road. It's crucial to address this code promptly to ensure safe driving conditions and maintain your vehicle’s performance. If you notice any symptoms associated with B074C, such as unusual steering feedback or warning lights on your dashboard, it's advisable to have your vehicle diagnosed and repaired as soon as possible.

Symptoms

Common symptoms when B074C is present:

  • The check engine light or power steering warning light is illuminated on the dashboard, indicating a fault.
  • Steering feels heavy or unresponsive, especially at low speeds, leading to difficulty in maneuvering the vehicle.
  • Unusual noises or vibrations occur while steering, which may indicate a deeper issue within the steering system.
  • The vehicle may enter a reduced power mode, limiting steering assistance and making it challenging to drive.
  • Inconsistent steering response when turning, which might cause the vehicle to drift or feel unstable.

Possible Causes

Most common causes of B074C (ordered by frequency):

  1. The most common cause of DTC B074C is a faulty steering angle sensor, which occurs in about 60% of cases. This sensor is crucial for providing the control module with real-time steering data.
  2. A second common cause is damaged wiring or connectors related to the steering angle sensor, which can interrupt the signal and lead to this code being triggered.
  3. Thirdly, software issues within the vehicle’s control module can also contribute to the B074C code, and these may often be resolved with a simple software update.
  4. Less common but serious causes include failures in the power steering control module itself, which can lead to total loss of steering assistance.
  5. A rare cause could be a malfunctioning steering rack, which can affect the entire steering system and requires immediate attention.
