Can I drive my car with B0087 or should I stop immediately?
It's advised not to drive the vehicle until the issue is resolved, as the airbag may not deploy in an accident, increasing the risk of injury.
How can I diagnose B0087 myself using GeekOBD APP?
Using the GeekOBD APP, you can read the diagnostic codes and review freeze frame data to understand the conditions under which the B0087 code was triggered.
What vehicles are most commonly affected by B0087?
B0087 is frequently reported in 2005-2010 Honda Accord and 2010-2018 Toyota Camry models, among others. Checking for recalls related to the airbag system is advised.
How can I prevent B0087 from happening again?
Regular maintenance and inspections of the airbag system, keeping the vehicle dry, and addressing any electrical issues promptly can help prevent B0087 from recurring.
What is B0087?
The B0087 diagnostic trouble code (DTC) indicates a fault in the airbag system, specifically related to the passenger side airbag sensor. This code is often triggered when the vehicle's onboard diagnostics detects an issue with the signal from the airbag sensor, which may be due to a malfunction in the sensor itself, wiring issues, or a problem with the airbag control module. When this code is present, it means that the airbag system may not deploy properly in the event of a collision, posing a significant safety risk. Common vehicles affected by this code include the 2005-2015 Honda Accord and the 2010-2018 Toyota Camry. Drivers may notice the airbag warning light illuminated on the dashboard, and it’s crucial to address this issue promptly to ensure passenger safety.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0087 is present:
- The airbag warning light stays on constantly, indicating a fault in the airbag system.
- You may experience intermittent warnings or alerts related to airbag deployment while driving.
- In some cases, the vehicle may display a message on the dashboard indicating a fault in the airbag system.
- There might be unusual noises coming from the dashboard area, often linked to the airbag control module.

Possible Causes
Most common causes of B0087 (ordered by frequency):
- {'cause': 'Faulty airbag sensor', 'likelihood': '60%', 'details': 'The most common cause is a malfunctioning airbag sensor that fails to provide accurate readings.'}
- {'cause': 'Wiring issues', 'details': 'Damaged, corroded, or loose wiring connections can disrupt the signal sent from the sensor to the control module.'}
- {'cause': 'Control module failure', 'details': 'A failing airbag control module can also trigger the B0087 code, often requiring replacement.'}
- {'cause': 'Impact damage', 'details': 'Accidents or impacts that affect the airbag sensor can cause faults, even in the absence of visible damage.'}
- {'cause': 'Water intrusion', 'details': 'Water damage from leaks can corrode connections or sensors, leading to code B0087.'}
