Resolver Sensor Repair procedures
Inspection
Hybrid Drive Motor
- 1. Inspect the resolver sensor resistance.


- If the resolver sensor needs to be replaced, replace the hybrid drive motor assembly.
(Refer to Hybrid Motor Assembly - "Hybrid Drive Motor Assembly")
Hybrid Starter Generator (HSG)
- Inspect the resolver sensor resistance.


- If the resolver sensor needs to be replaced, replace the HSG assembly.
(Refer to Hybrid Motor Assembly - "Hybrid Starter Generator")
Resolver Calibration
Perform the resolver calibration using the KDS after replacing or reinstalling the below components.
- Hybrid Drive Motor installation
- Hybrid Starter Generator (HSG) installation
- Motor Control Unit (MCU) replacement
- Engine clutch system replacement

Motor Temperature Sensor
Description
Temperature of the motor largely influences the motor output. Hence, when the motor is overheated,
major components such as the IPM or stator coil may get damaged or affected. To prevent this, a
motor temperature sensor is embedded in the motor to control the motor torque according to its
temperature.
