Hyundai Ioniq (AE): Hybrid Motor Control System / Motor Temperature Sensor. Repair procedures

Inspection

Check the temperature sensor resistance.

[Hybrid drive motor]

Measuring equipment : Multimeter

Category	Inspection area	Inspection criteria	Remarks
Resistance (Temperature sensor)	Pin 4 - 8	8kΩ (30°C / 86°F) - 20kΩ (10°C / 50°F)	10 - 30°C / 50 - 86°F

[Hybrid starter generator (HSG)]

Measuring equipment : Multimeter

Category	Inspection area	Inspection criteria	Remarks
Resistance (Temperature sensor)	Pin 4 - 9	126.8 kΩ	Based on ambient temperature (20°C)

2.	If you need to replace the temperature sensor, replace the HSG assembly. (Refer to Hybrid Motor Assembly - "Hybrid Starter Generator".)
