DESCRIPTION

The shift stroke sensor is mounted on the shift and select actuator, and detects the shift 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 shift 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 the voltage signal and send it to the TCM. The TCM judges the shift motor operating condition (which gear is selected: reverse, 1st, 3rd and 5th or 2nd, 4th and 6th) based on the signal from the shift stroke sensor.

The main and sub circuits in the shift stroke sensor have the same output characteristics.

The sensor construction and operation of the shift stroke sensor are basically the same as those of the clutch stroke sensor.
