What is B0970?

Diagnostic Trouble Code (DTC) B0970 indicates an issue with the Power Steering Control Module. This code is primarily found in vehicles equipped with electronic power steering (EPS) systems, such as the 2015-2018 Honda Accord, Honda CR-V, and several other makes and models. The power steering control module is responsible for regulating the amount of assistance provided to the driver, making steering easier at lower speeds. When the module detects a fault, it triggers the B0970 code, which can illuminate the check engine light or the power steering warning light on the dashboard. Drivers may experience increased steering effort, especially during parking maneuvers, as the system may revert to manual steering mode. Neglecting this issue can lead to steering difficulties, which pose safety risks during vehicle operation. A thorough diagnostic process is essential to pinpoint the exact cause, which may range from electrical issues, like wiring problems or poor connections, to component failures within the power steering system itself. Understanding the B0970 code is crucial for ensuring safe driving conditions and maintaining the vehicle's performance.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B0970 is present:

  • The check engine light or power steering warning light illuminates on the dashboard, indicating a potential issue with the steering system.
  • Increased steering effort, particularly noticeable when maneuvering at low speeds or during parking, can lead to driver fatigue and difficulty controlling the vehicle.
  • Unusual noises, such as whining or grinding, may occur when steering, pointing to potential mechanical issues within the power steering system.
  • Intermittent steering assistance, where the power steering works at times but fails at others, can create an unpredictable driving experience.
  • Poor vehicle handling, especially during tight turns, can result from the loss of power steering assistance, increasing the risk of accidents.

Possible Causes

Most common causes of B0970 (ordered by frequency):

  1. The most common cause of the B0970 code is a faulty Power Steering Control Module, which has a likelihood of around 60%. This can result from internal circuit failures or software issues.
  2. Wiring problems, such as frayed or corroded connectors, can cause poor communication between the control module and the vehicle's electronic systems, accounting for about 25% of cases.
  3. A malfunctioning steering angle sensor may trigger the B0970 code as it provides critical data to the power steering module; proper calibration and testing can help prevent this issue.
  4. Less commonly, issues within the power steering pump itself, such as leaks or mechanical failures, may lead to the B0970 code, but these occurrences are rare.
  5. In some instances, a power supply issue, such as a weak battery or charging system problems, can affect module performance, although this is not frequently the primary cause.
