What is B0618?

DTC B0618 indicates a problem with the steering angle sensor, which is crucial for your vehicle's stability control systems. This sensor measures the angle of the steering wheel and communicates this data to the vehicle's computer. If there's an issue with the sensor or its wiring, it can lead to inaccurate readings, resulting in poor handling and stability control. This code can trigger a warning light on your dashboard, alerting you that the vehicle's safety systems may not function correctly. For instance, drivers of 2013-2017 Honda Accord or 2014-2018 Toyota Camry may experience this code. Ignoring this warning could compromise your vehicle's handling, especially in slippery conditions or during emergency maneuvers. It’s essential to address the B0618 code promptly to ensure your vehicle maintains its handling characteristics and safety features, as the steering system directly affects how your vehicle responds to driver inputs. Neglecting this issue could lead to increased repair costs down the line and may affect your vehicle's insurance coverage if an accident were to occur.

Symptoms

Common symptoms when B0618 is present:

  • The check engine light remains illuminated, indicating an issue with the steering system.
  • Steering feels loose or unresponsive, making it difficult to control the vehicle accurately.
  • The stability control light may flash intermittently, signaling potential loss of traction.
  • Unusual noises when turning the steering wheel, which could indicate a failing sensor or related components.
  • Erratic handling or difficulty maintaining a straight line while driving due to improper sensor feedback.

Possible Causes

Most common causes of B0618 (ordered by frequency):

  1. The most common cause of the B0618 code is a faulty steering angle sensor, with a likelihood of about 60%. This could be due to wear and tear or manufacturing defects.
  2. Another frequent cause is damaged wiring or poor connections, which can occur from corrosion or physical damage, accounting for approximately 25% of cases.
  3. A misaligned steering wheel can also trigger this code, often due to improper installation during repairs, which can be prevented by ensuring proper calibration during maintenance.
  4. Less commonly, a malfunctioning Electronic Control Unit (ECU) may be responsible, requiring more extensive diagnostics and repair, though this is rare.
  5. Lastly, a failed clock spring, which connects the airbag system to the steering wheel, can also lead to this code, but it is not as frequently encountered.
