Kia Niro 2017 (DE HEV) Service Manual / Service Highlight / Hybrid Motor Control System / Resolver Sensor Repair procedures

Inspection

Hybrid Drive Motor

Inspect the resolver sensor resistance.

Item	Pin	Specification	Remarks
Resistance (Resolver sensor)	1 - 5	11.7 Ω ± 10 %	At room temperature 68°F (20°C)
	2 - 6	34.5 Ω ± 10 %
	3 - 7	29.5 Ω ± 10 %

2.	If the resolver sensor need to be replaced, hybrid drive motor assembly should be replaced. (Refer to Hybrid Motor Assembly - "Hybrid Drive Motor Assembly")

Inspect the resolver sensor resistance.

Item	Pin	Specification	Remarks
Resistance (Resolver sensor)	1 - 4	13.8 - 17.8 Ω	At room temperature 68°F (20°C)
	2 - 5	26.2 - 30.2 Ω
	3 - 6	26.2 - 30.2 Ω

2.	If the resolver sensor need to be replaced, HSG assembly should be replaced. (Refer to Hybrid Motor Assembly - "Hybrid Starter Generator")
