DTC P0705-13: Transmission Range Sensor "A" Circuit Open; DTC P0705-62: Transmission Range Sensor "A" Signal Compare Failure [10/2022 - ]: Description

WARNING: This page is about a different car, the 2025 Toyota Highlander, 2024 Toyota Highlander, and 2023 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.

The park/neutral position switch assembly and transmission control switch (shift lock control unit assembly) detect the shift lever position and send signals to the ECM.
