DESCRIPTION

The clutch stroke sensor is mounted on the clutch actuator, and detects the clutch master cylinder position of the clutch actuator. The sensor consists of a sensor arm, a 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 clutch actuator is operating, 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 them to the TCM. The TCM judges the clutch condition (whether the clutch is engaged, disengaged, or partially engaged) based on the signal from the clutch stroke sensor.

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