What P2609 means
Source: SAE J2012 / OBD-IIP2609 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 Ram and its owners have filed about it; the code’s page across every make has the whole file.

It is a documented one: NHTSA's files hold 6 manufacturer filings and 6 owner reports naming P2609 on 5 Ram 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.

2017 2500 (3 documents), 2016 2500 (3 documents), 2016 3500 (3 documents).
Does P2609 on a Ram 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.
