A model year is listed because the code is named in its own record — a bulletin filed against it, or an owner’s complaint about it — not because every one of these vehicles sets it. Counts are documents in NHTSA’s files, not failure rates.

What P0867 means

Source: SAE J2012 / OBD-II

P0867 sits in the generic range of the OBD-II standard, so it means the same thing on every vehicle sold in the United States — but WhichTrim does not carry a definition for it and will not invent one. What is on this page is the record: who named it and on what.

A stored code names the test that failed, never the part that caused it. The record above is what Subaru and its owners have filed about it; the code’s page across every make has the whole file.

Common questions

Source: NHTSA files and the OBD-II standard

Is P0867 a known problem on Subaru vehicles?

It is a documented one: NHTSA's files hold 25 manufacturer filings and 3 owner reports naming P0867 on 25 Subaru model years (2019–2024). Whether it is a problem on one particular car is a diagnosis, not a count — but a bulletin that names the code on your model year is the place to start.

Which Subaru models does P0867 appear on most?

2020 Ascent (2 documents), 2021 Legacy (2 documents), 2020 Outback (2 documents).

Does P0867 on a Subaru mean it is recalled?

No. Recalls are filed by campaign and matched by VIN; no recall is triggered by a scan tool. Check the VIN at nhtsa.gov/recalls, or open the model year's page here for the campaigns filed against it.
