DESCRIPTION

The select stroke sensor is mounted on the shift and select actuator, and detects the select position of 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 the voltage signals and send it to the transmission control ECU. The transmission control ECU judges the select motor operating condition (which gear shift fork shaft is selected: No. 1, No. 2 or No. 3) 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.

INSPECTION PROCEDURE

Note

In select stroke sensor replacement, perform [Initialization and Learning] Click here and [Synchronization Position Calibration] Click here after installing the sensor.

If the sensor is installed without performing [Initialization and Learning] procedure and [Synchronization Position Calibration] procedure, it may cause driving performance degradation or system component breakage.

Tech Tips

When only DTC P0905 is set, replace the select stroke sensor.
