What is B0290?

The diagnostic trouble code B0290 indicates a problem with the airbag system, specifically related to the passenger airbag sensor. This code is commonly found in several Toyota and Honda models, particularly those manufactured between 2005 and 2018. When the B0290 code triggers, it typically means that the vehicle’s onboard diagnostics have detected an issue with the airbag sensor circuit. This could be due to a malfunction in the sensor itself, wiring issues, or a problem with the airbag control module. In real-world terms, if this code appears, your airbag system may not deploy correctly in the event of a collision, posing a significant safety risk. It is crucial to address this issue promptly to ensure the safety of all vehicle occupants. Drivers may notice symptoms such as a persistent airbag warning light on the dashboard, indicating that the system needs immediate attention. Ignoring this code can result in increased repair costs down the line and, more importantly, could jeopardize passenger safety. Therefore, if you see the B0290 code, it’s essential to seek professional help to diagnose and rectify the problem.

Symptoms

Common symptoms when B0290 is present:

  • The airbag warning light on the dashboard remains illuminated, signifying a malfunction in the airbag system.
  • A noticeable delay in the airbag deployment during test scenarios, indicating potential failure during an actual accident.
  • Decreased functionality of the passenger airbag, which may not deploy during a collision, putting passengers at risk.
  • Electrical problems such as flickering dashboard lights, which could indicate issues with the airbag system wiring.
  • Unusual noises from the dashboard area, which may suggest loose connections or faults within the airbag system.

Possible Causes

Most common causes of B0290 (ordered by frequency):

  1. The most common cause of B0290 is a faulty passenger airbag sensor, which accounts for about 60% of cases. This can occur due to wear and tear or manufacturing defects.
  2. Another frequent cause is damaged wiring or poor connections in the airbag system, which can lead to intermittent faults or complete sensor failure.
  3. A malfunctioning airbag control module can also trigger this code, though it is less common. This module is responsible for managing airbag deployment.
  4. Less common but serious causes include water damage to the airbag system components or a failed impact sensor, which could prevent airbags from deploying.
  5. In rare cases, the presence of aftermarket modifications or poor-quality repairs can affect the airbag system's integrity and lead to this code.
