DESCRIPTION

*a

Shift and Select Actuator Operation

*b

Shift Direction

*c

Select Direction

The select stroke sensor is mounted on the shift and select actuator, and detects the select position of the shift and select lever shaft. The sensor consists of a sensor arm, magnetic yoke and 2 Hall ICs. This sensor is a non-contact type, and uses Hall-effect elements (Hall ICs: main and sub), in order to yield accurate signals.

When the shift and select actuator is operating in the select direction, the magnetic yoke that is coaxially positioned on the sensor arm is rotated and the magnet position changes. The Hall ICs convert the magnet position change into voltage signals and send them to the TCM. The TCM judges the select motor operating condition (which gear shift fork shaft is selected: No. 1, No. 2, No. 3 or reverse) based on the signal from the select stroke sensor.

The main and sub circuits in the select stroke sensor have the same output characteristics. The sensor construction and operation of the select stroke sensor are basically the same as those of the clutch stroke sensor.
