Kia Sportage: Input Speed Sensor

Kia Sportage Third generation (SL) - (2011-2016) - Service and Repair Manual / Automatic Transaxle System / Automatic Transaxle Control System / Input Speed Sensor

Description and Operation

 Description

Input speed sensor is a vital unit that 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, damper clutch control, gear setting control, line pressure control, clutch activation pressure control, and sensor fault analysis.
