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