TRANSMISSION RANGE (TR) SWITCH FUNCTION [SJ6A-EL]

E5U051319200N01

• The TR switch sends information on which range 

is selected in the automatic transmission using a 
combination of the position circuit terminals, and 
its functions are as follows:

1. Enables engine starting only in P or N 

positions

2. Used as shifting control signals

TURBINE SENSOR, VEHICLE SPEED SENSOR (VSS) CONSTRUCTION/OPERATION [SJ6A-EL]

E5U051319200N02

• The turbine sensor detects the rotation speed of the direct and reverse disc clutch case, and sends it to the 

TCM as a signal.

• The VSS detects the rotation speed of the parking gear and sends it to the TCM as a signal.

• A magnetic pick sensor which has high detection accuracy has been adopted for each sensor. When the rotor 

rotates, air gap between the sensor and detection projections varies, magnetic flux which passes through the 
sensor coil increases and decreases, and electromotive force is generated in the coil. This generated voltage is 
shown as alternative current since the current direction while the projections are approaching the sensor is 
reversed from that of when the projections are moving away from the sensor.
