What is B02D3?

The DTC B02D3 code refers to a problem with the rear passenger side door latch sensor. This trouble code is typically triggered when the vehicle's onboard diagnostic system detects an issue with the latch mechanism or its associated wiring. In practical terms, this means that your vehicle may have difficulty recognizing whether the rear passenger side door is securely closed. This can lead to safety concerns, as the door may inadvertently open while driving, posing a risk to passengers. Additionally, the inability to confirm the door’s status can trigger warning lights on the dashboard, leading to confusion or concern for the driver. Common vehicles affected by this code include the 2015-2020 Ford Explorer and other models within the Ford lineup that utilize similar latch mechanisms. Owners may experience symptoms like the rear door not unlocking or locking properly, and this can lead to further complications if left unaddressed. Repairing the issue usually involves inspecting the latch assembly, the wiring, and possibly replacing the latch sensor itself, which can be a moderately complex task depending on the vehicle’s design.
