DTC B166A: Pressure Sensor Difference for Front Door [08/2020 - ]: Description
WARNING: This page is about a different car, the 2025 Toyota RAV4, 2024 Toyota RAV4, 2023 Toyota RAV4, 2022 Toyota RAV4, and 2021 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
The side airbag pressure sensor LH and side airbag pressure sensor RH detect impacts to the vehicle through changes in pressure inside the front doors caused by deformation of the outer side of the front doors and send signals to the airbag ECU assembly.
Based on the signals sent by the side airbag pressure sensor, the airbag ECU assembly determines if the SRS should be deployed.
If the difference between the pressure detected by the side airbag pressure sensor LH and the pressure detected by the side airbag pressure sensor RH exceeds a certain value a certain number of times, the airbag ECU assembly will output DTC B166A.
