Monitor Description
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.
This DTC indicates a short to ground in the ATF temperature sensor circuit. The ATF temperature sensor converts the ATF temperature into an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature, and can detect a short to ground in the ATF temperature sensor circuit. If the resistance value of the ATF temperature sensor is below 79 Ω*, the ECM interprets this as a malfunction of the ATF temperature sensor or in the wire harness, illuminates the MIL and stores this DTC.
*: 150°C (302°F) or higher is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked in the Data List.
