P0C73 has a source-scoped interpretation in a manufacturer document. Check the raw form, vehicle conditions and original bulletin before using it.
This meaning belongs to the cited manufacturer document and its conditions. It is not a universal code definition, a VIN-specific match, a driving clearance or a parts diagnosis. Independent safety review remains pending.
This Hyundai document supports only its stated code and vehicle context. The code alone cannot identify a failed part, prove that another make uses the same definition, or clear a car for driving. Compare your full scan with the current exact-vehicle service information.

What the manufacturer document says
The same root can have a different meaning or role in another module or vehicle. Preserve the full raw code and suffix rather than applying this table to every car.
| Raw form | Meaning in source | Document | Case context |
|---|---|---|---|
| P0C73 | Motor-electronics coolant pump A control performance | Hyundai 14-HC-001 | Sonata Hybrid YF pump codes: verify commanded cooling-pump operation |
| P0C73 | Motor-electronics coolant pump A control performance | Kia ELE 211 Rev1 | Kia Niro P2600/P0C73: partial pump repair versus complete replacement |
| P0C7300 | Motor-electronics coolant pump A control-performance indication | Kia ELE386 / SA617 | 2025 Carnival Hybrid P0C7300: MCU logic update, not assumed pump failure |
Vehicle scope recorded in the source
- Hyundai Sonata Hybrid · year not established · HEV
- Kia Niro · 2019 · HEV; 2019-01-23
- Kia Niro Plug-in Hybrid · 2019 · PHEV; 2019-01-23
- Kia Carnival Hybrid · 2025 · HEV; 2025-03-19
What to record before clearing the code
- READY behavior and exact warning text
- Codes and the point at which propulsion becomes abnormal
- Whether coolant was recently serviced
- Build date and HEV/PHEV identification
- Note other codes and the exact dashboard message; a generic reader may miss the affected module.
Questions before a repair or part order
- Do not apply the open-ended 2011~ label to later Sonata platforms or substitute the Kia pump procedure.
- Do not recommend the full assembly before the contamination/terminal inspection, or sell kit subcomponents as individually available.
- Do not import the 2019 Niro pump-replacement recommendation into this Carnival software case.
- Does the current manufacturer document cover this VIN, engine, build date and symptom?
- Is a recall, warranty or newer service communication relevant? A bulletin alone is not free-repair eligibility.
How to use this research note
The source document is historical and may have a later revision. Its cited vehicle table is a condition to verify, not a complete list of affected VINs. A code can be secondary to another fault. If braking, steering, propulsion, temperature, smoke, fuel or high-voltage behavior is unsafe, stop safely and seek qualified help rather than using this page to continue driving.
