What is B07A6?

The DTC code B07A6 is a diagnostic trouble code that indicates an issue with the vehicle's steering angle sensor, particularly its signal being out of range or faulty. This code is common in vehicles equipped with advanced driver-assistance systems (ADAS) that rely on accurate steering input for functionality. When the steering angle sensor fails or provides erratic readings, it can lead to several issues, including compromised stability control and inaccurate lane-keeping assistance. If your vehicle's onboard diagnostic system detects this code, it is crucial to address it promptly to maintain optimal driving safety and performance. Many owners of 2015-2018 Honda Accord and similar vehicles may experience symptoms such as the check engine light illuminating or erratic steering behavior. Ignoring this code may lead to more severe issues over time, including increased wear and tear on the steering mechanism and related components. Therefore, understanding the B07A6 code is essential for every vehicle owner to ensure safety and reliability on the road.

Symptoms

Common symptoms when B07A6 is present:

  • Check engine light stays on constantly, indicating a persistent issue with the steering system and requiring immediate diagnostic attention.
  • Steering feels loose or unresponsive, leading to a disconcerting driving experience and potential safety hazards.
  • Increased difficulty in lane-keeping assistance features, which may cause the vehicle to drift unexpectedly, raising safety concerns.
  • Erratic behavior of electronic stability control systems, which can compromise vehicle stability under various driving conditions.
  • Abnormal noises from the steering column, such as grinding or clicking, which may indicate underlying problems with the steering mechanism.

Possible Causes

Most common causes of B07A6 (ordered by frequency):

  1. The most common cause of the B07A6 code is a faulty steering angle sensor, occurring in approximately 60% of cases. This sensor can wear out or become misaligned over time due to regular use.
  2. Another frequent cause is wiring issues, such as damaged or corroded wiring harnesses, which can disrupt the signal sent from the steering angle sensor to the vehicle's computer.
  3. A third cause could be a software glitch in the vehicle's electronic control module (ECM), leading to improper readings from the sensor. Regular software updates can help mitigate this risk.
  4. Less common but serious causes include physical damage to the steering mechanism or the steering column, which can severely affect steering performance.
  5. Lastly, a rare cause might be related to incorrect installation of replacement parts, particularly after repairs involving the steering system, which can lead to sensor misalignment.
