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 transmission control ECU. The transmission control ECU judges the shift motor operating condition (whether the gear is shifted to 1st, 3rd and 5th or 2nd, 4th and Reverse) based on the signal from the shift stroke sensor.

A0135WUE04

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.

INSPECTION PROCEDURE

Note

In shift 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] and [Synchronization Position Calibration], it may cause driving performance degradation or system component breakage.

Tech Tips

When only DTC P0915 is set, replace the shift stroke sensor.
