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.

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

What P0A43 means

P0A43 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 Chrysler and its owners have filed about it; the code’s page across every make has the whole file.

Is P0A43 a known problem on Chrysler vehicles?

It is a documented one: NHTSA's files hold 57 manufacturer filings and 17 owner reports naming P0A43 on 11 Chrysler model years (2017–2023). 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 Chrysler models does P0A43 appear on most?

2022 Pacifica (14 documents), 2023 Pacifica (12 documents), 2021 Pacifica (10 documents).

Does P0A43 on a Chrysler 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.
