Monitor Description

The ATF temperature sensor converts the ATF temperature into an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an open or short in the ATF temperature circuit. If the resistance value of the ATF temperature is below 25 Ω*1 or higher than 156 kΩ*2, the ECM interprets this as a fault in the ATF temperature sensor or wiring. The ECM stores a DTC, and the ATF temperature warning light blinks or a message is displayed in the combination meter.

HINT: 

• *1: 150°C (302°F) or higher is indicated regardless of the actual ATF temperature.
• *2: -40°C (-40°F) is indicated regardless of the actual ATF temperature.
• The ATF temperature can be checked on the Techstream display.
