Transaxle fluid temperature (TFT) sensor circuit range/performance (stuck)

DETECTION 

CONDITION

• When all conditions below are satisfied.

— When 180 seconds have passed after engine is started, vehicle is driven for 150 seconds or more at 

vehicle speed between 25 – 59 km/h {15 – 36 mph}, then 60 km/h {37 mph} or more for 100 seconds 
or more.
