Hyundai Creta: Automatic Transaxle Control System / Input Speed Sensor
Description and operation
| Description |
| • |
Input speed sensor uses an electric current type hall sensor in which
the current is changed by the magnetic variation.
|
| • |
Input speed sensor (A) and output speed sensor are integrated and installed
in the transaxle.
|
| • |
Measures the rate of rotation of the input 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.
