Inspection [08/2020 - ]: Procedure
WARNING: This page is about a different car, the 2024 Lexus ES 250, 2023 Lexus ES 250, 2022 Lexus ES 250, and 2021 Lexus ES 250. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY NOTE:
Both the park/neutral position switch assembly and transmission control shaft lever are available in two different shapes due to design changes. As they are not compatible with each other, when replacing the park/neutral position switch assembly, make sure to also replace the transmission control shaft lever as a set.
- Measure the resistance according to the value(s) in the table below when the transmission control shaft lever is moved to each position.
