Error conversion of voltage drops of NTC sensors to temperature

The MC33772C BMS slaves are connected to the S32K144EVB evaluation board via TPL lines. I program the evaluation board using the Model-Based Design Toolbox from NXP in Simulink. NTC sensors are mounted on the MC33772C, and I need to read the temperatures measured by the evaluation board. However, the temperature conversions are incorrect. The analog voltages from the GPIOs of the MC33772C are correct, so I believe the issue lies with the conversion process. The conversion parameters, such as the NTC fixed resistance and NTC reference resistance, are correctly set. I tried configuring the GPIOs as ratiometric analog inputs, but the temperature conversions are still incorrect. I can't determine the cause of the problem.
