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 P0731 means

P0731 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.

Common questions

Source: NHTSA files and the OBD-II standard

Is P0731 a known problem on Ram vehicles?

It is a documented one: NHTSA's files hold 15 manufacturer filings and 4 owner reports naming P0731 on 7 Ram model years (2016–2023). 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 Ram models does P0731 appear on most?

2022 3500 (5 documents), 2016 1500 (4 documents), 2020 1500 (3 documents).

Does P0731 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.
