DTC TURBINE REVOLUTION SENSOR
Description INFOID:0000000004305450
The turbine revolution sensor (power train revolution s ensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automat ic transaxle. The vehicle speed sensor A/T (Revolution
sensor) is located on the output side of the automatic transaxle. With the two sensors, input and output rpms
are accurately detected. As a resu lt, optimal shift timing during deceleration and shift quality can be improved.
