DTC C1353-01: Pressure Sensor (Wh1) - Electrical: General Description
WARNING: This page is about a different car, the 2024 Kia Sorento. However, it is still accessible from the selected car via links, so may be relevant.
The pressure sensor, installed in the Integrated Electronic Brake (IEB) module, converts the brake pressure to judge the driver's brake intention when the ESP/DBC/AVH program is operated. When pressure is applied to the sensor, the resistance of the sensor's strain gauge changes. The change in resistance changes the voltage output from the sensor.
