What P0339 means

P0339 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 Jeep and its owners have filed about it; the code’s page across every make has the whole file.

Is P0339 a known problem on Jeep vehicles?

It is a documented one: NHTSA's files hold 11 manufacturer filings and 3 owner reports naming P0339 on 8 Jeep model years (2016–2020). 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 Jeep models does P0339 appear on most?

2018 Wrangler (3 documents), 2018 Renegade (2 documents), 2017 Renegade (2 documents).

Does P0339 on a Jeep 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.
