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 Ford owners said

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

What P2704 means

Source: SAE J2012 / OBD-II

P2704 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 Ford 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 P2704 a known problem on Ford vehicles?

It is a documented one: NHTSA's files hold 432 manufacturer filings and 3 owner reports naming P2704 on 51 Ford model years (2017–2026). 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 Ford models does P2704 appear on most?

2020 Explorer (24 documents), 2022 Explorer (16 documents), 2021 Explorer (16 documents).

Does P2704 on a Ford 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.
