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 Ram owners said

Source: NHTSA complaint database

Owners’ own words, scrubbed of anything identifying. Unverified reports filed with NHTSA — what was said, not a finding that it was true.

The codes are P0365 indicating the entire PCM is failing or failed and P0606 an internal processor code which has to do with the computers not being able to calculate wheel speeds with the transmission and engine and how much gas to spray

What P0365 means

Source: SAE J2012 / OBD-II

P0365 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 P0365 a known problem on Ram vehicles?

It is a documented one: NHTSA's files hold 16 manufacturer filings and 1 owner report naming P0365 on 14 Ram model years (2016–2019). 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 P0365 appear on most?

2018 1500 (2 documents), 2019 ProMaster (2 documents), 2016 ProMaster (2 documents).

Does P0365 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.
