P2797 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 Subaru 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 |
|---|---|---|---|
| P2797 | Auxiliary transmission-fluid pump A performance or stuck-off indication | Subaru 16-145-23R | Subaru P2797 after stop/start: a TCM calibration branch |

What to record before clearing the code
- Whether the code appeared during a stop/start restart
- Build and engine identification
- Prior TCM updates
- 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 condemn the CVT or auxiliary pump from P2797 alone, and do not append a generic learning requirement.
- 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.
