A model year appears here because the code is named in its record, not because every one of these vehicles sets it. Counts are mentions in the federal files, not failure rates — nobody publishes the denominator.

P0139 by make
The same record, one make at a time: the model years, bulletins and owner reports that name P0139 on that maker’s vehicles.
What it gets filed under
14 manufacturer filings name P0139. Start with what the maker wrote down.
A code names the test that failed, not the part. A bulletin that names it is often a diagnosis someone has already written down — quote its number at the service desk.

- A25-040 Service bulletin2025-06-25 · Fuel/Propulsion System
- Service Bulletin - The MIL comes on with DTC P0139 (secondary heated oxygen sensor slow response) due to the ECM/PCM misinterpreting the secondary heated oxygen sensor output and sets DTC P0139.
- TSB 24-2066 Service bulletin2024-03-12 · Electrical System — Software
- This TSB supersedes article 24-2036 to update the vehicles affected. Some 2023-2024 F-Super Duty pickup vehicles built on or before 02-Jan-2024 equipped with a 6.7L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTC) P0133, P0139, and/or P0145 stored in the powertrain control module (PCM). This may be due to the software in the PCM and does not affect vehicle operation.

- Some 2023-2024 F-Super Duty chassis cab vehicles built on or before 02-Jan-2024 equipped with a 6.7L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTC) P0133, P0139, and/or P0145 stored in the powertrain control module (PCM). This may be due to the software in the PCM and does not affect vehicle operation. To correct the condition, reprogram the PCM and transmission control
- TSB-16-13-002 Service bulletin2016-04-11 · Electrical System — Software

What P0139 means
Source: SAE J2012 / OBD-IIP0139 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. It is the starting point of a diagnosis, not its conclusion — the same code has several possible causes and the cheap one is not always right.
Common questions about P0139
Source: NHTSA files and the OBD-II standardCan I keep driving with P0139 stored?
Nobody can answer that from the code alone, and a site that does is guessing. A steady light means a fault was logged and the car should be checked soon; a flashing light means a severe misfire — slow down and get it seen as soon as possible, because severe misfire can quickly damage the catalytic converter. The safe read of this page is the mileage and the components, not permission.
Does a code mean the car is recalled?
No. Recalls are filed by campaign and matched by VIN, and none of them are triggered by a scan tool. If you want to know whether an open recall applies to one specific vehicle, check the VIN at nhtsa.gov/recalls — that is the only source that settles it.
Why do the counts here differ from other sites?
Because these are not estimates. Every number on this page is a count of documents in NHTSA's own files: manufacturer communications that name the code in their filed summary, and owner complaints that name it in the narrative. We do not model, weight or extrapolate them.
Will clearing the code fix it?
Clearing turns the light off and erases the freeze-frame data a technician would have used to work out what happened. If the condition is still there the code returns, usually within a few drive cycles, and the diagnosis now starts from less information than before.
