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.

It is a documented one: NHTSA's files hold 41 manufacturer filings and 5 owner reports naming P0303 on 16 Lincoln model years (2016–2026). 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 Lincoln models does P0303 appear on most?

2017 MKZ (8 documents), 2024 Corsair (5 documents), 2017 Continental (4 documents).

Does P0303 on a Lincoln 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.
