Regular maintenance of your vehicle's steering system, including inspections of wiring and connections, can help prevent DTC B0C37. Additionally, avoid aftermarket modifications that could interfere with the steering system's electronics.

What is B0C37?

DTC B0C37 is a diagnostic trouble code that indicates a fault in the steering wheel angle sensor circuit. This sensor plays a crucial role in ensuring the stability and control of your vehicle, particularly in systems like electronic stability control (ESC) and traction control. When this code is triggered, it means that the vehicle's computer has detected an issue with the input from the steering angle sensor, which could lead to impaired handling and increased risk of accidents. In practical terms, this may manifest as unresponsive steering, difficulty in maneuvering, or the activation of warning lights such as the ABS or traction control lights. Vehicles like the 2016-2020 Ford Explorer, Ford Edge, and some Lincoln models are particularly prone to this issue due to the electronic nature of their steering systems. If left unaddressed, the malfunction could lead to serious driving safety concerns. Thus, understanding the implications of code B0C37 and acting swiftly is important for the safety and performance of your vehicle.

Symptoms

Common symptoms when B0C37 is present:

  • The check engine light illuminates alongside the ABS or traction control warning lights, indicating a potential issue with vehicle stability systems.
  • Drivers may experience unresponsive steering, making it difficult to control the vehicle effectively, especially during turns.
  • Fuel economy may decrease due to increased strain on the vehicle’s systems, potentially reducing efficiency by 10-15%.
  • The vehicle may exhibit erratic behavior in stability control systems, such as unexpected braking or loss of traction during acceleration.
  • In some cases, drivers report a grinding noise or vibration when turning the steering wheel, indicating possible sensor malfunction.

Possible Causes

Most common causes of B0C37 (ordered by frequency):

  1. The most common cause of DTC B0C37 is a malfunctioning steering angle sensor, with a likelihood of about 60%. This sensor can fail due to wear and tear or electrical issues.
  2. Another cause could be damaged wiring or loose connections in the sensor circuit, which accounts for approximately 25% of cases. Corrosion or frayed wires can interrupt signal transmission.
  3. Improper installation or calibration after a steering column repair can also trigger this code, emphasizing the need for accurate service.
  4. Less common, but serious, is a malfunction in the vehicle’s body control module (BCM) which can disrupt sensor communication. This is a rare occurrence but requires immediate professional diagnosis.
  5. A rare cause could be interference from aftermarket modifications, such as steering wheel replacements or electronic upgrades, affecting the sensor’s performance.
