What P2610 means
Source: SAE J2012 / OBD-IIP2610 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 Toyota 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 standardIs P2610 a known problem on Toyota vehicles?
It is a documented one: NHTSA's files hold 26 manufacturer filings and 2 owner reports naming P2610 on 20 Toyota model years (2016–2020). 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 Toyota models does P2610 appear on most?
2016 Corolla (4 documents), 2016 Camry (2 documents), 2017 Corolla (2 documents).
Does P2610 on a Toyota 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.
