Turbine Speed Sensor 1, 2

TURBINE SPEED SENSOR 1, 2




Wheel speed sensors are hall element type sensors. Turbine speed sensor 1 detects the speed of the front sun gear, and turbine sensor 2 detects the speed of the front carrier. Each sensor sends pulse signals (60 pulses per rotation) to the TCM. From these two speed values, the TCM calculates the turbine speed and uses it for shifting control.
