Hyundai Creta: Automatic Transaxle Control System / Output Speed Sensor

Hyundai Creta GS 2014-2026 Service Manual / Automatic Transaxle System / Automatic Transaxle Control System / Output Speed Sensor

Description and operation

Description

•	Output speed sensor uses an electric current type hall sensor in which the current is changed by the magnetic variation.

•	Output speed sensor (A) and Input speed sensor are integrated and installed in the transaxle.

Functions

•	Measures the rate of rotation of the output shaft inside the transaxle and delivers the readings to the TCM.

•	The sensor provides critical input data that's used in feedback control, torque converter clutch control, gear setting control, line pressure control, clutch activation pressure control, and sensor fault analysis.
