Description and operation

Description

•	The sensor used is a thermistor (NTC) in which resistance changes with temperature variation.

•	When the TCM supplies power to sensor, the sensor output value changes depending on ATF temperature.

•	Oil temperature sensor is integrated with E module.

Repair procedures

Inspection

1.	Switch "OFF" ignition.

2.	Disconnect the main connector (A).

3.	Measure the resistance between + terminal (15) and - terminal (16).

Check that the resistance is within the specification.

Kia Stinger (CK) 2018-2023 Service Manual: Electric Power Steering

Description and operation Description EPS (Electric power steering, Column assist type) system is an engine operation independent steering system that uses an electric motor to assist the steering force. EPS control module controls the motor operation based on input signals from torque sensor and steering angle sensor via CAN (Controller Area Network), resulting in a more precise and timely control of steering assist thatn conventional engine-driven hydraulic systems.
