What is B0230?

The B0230 diagnostic trouble code (DTC) indicates a malfunction in the airbag system, specifically relating to the passenger airbag sensor. This code is often triggered by issues within the airbag control module or the wiring that connects it to the sensor itself. When this code is present, it signals that the passenger airbag may not deploy correctly in the event of a crash, posing a significant safety risk. The airbag system is designed to enhance occupant safety, and if the system is compromised, it could lead to severe injuries during an accident. Owners of vehicles affected by this code should treat it with urgency. Commonly affected models include the 2005-2010 Honda Accord and Toyota Camry, where the airbag system's reliability is critical. Ignoring this code could lead to a malfunctioning airbag, which would not deploy when needed, putting passengers at risk. Repairing the issue usually involves inspecting the wiring for damage, clearing any faults from the OBDII system, and possibly replacing the airbag sensor or control module if necessary.
