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 C1142 means

Source: SAE J2012 / OBD-II

C1142 is a manufacturer-specific code: the second character is a 1, which under the OBD-II standard hands the definition to whoever built the vehicle. The same code can mean one thing on a Ford and something unrelated on a Hyundai. Any site that prints a single definition for it is guessing.

A stored code names the test that failed, never the part that caused it. The record above is what Nissan and its owners have filed about it; the code’s page across every make has the whole file.

Is C1142 a known problem on Nissan vehicles?

It is a documented one: NHTSA's files hold 21 manufacturer filings and 2 owner reports naming C1142 on 20 Nissan 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 Nissan models does C1142 appear on most?

2022 Frontier (4 documents), 2021 Altima (1 document), 2020 Altima (1 document).

Does C1142 on a Nissan 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.
