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.
What it gets filed under
What owners said
Source: NHTSA complaint databaseOwners’ own words, one per nameplate, scrubbed of anything identifying. These are unverified reports filed with NHTSA — they are what was said, not a finding that it was true.
I investigated the code that was provided by JScan “P00AF� and discovered that numerous owners had experienced the same situation across all lines of vehicles that use the Gen 3 Ecodiesel
I have pictures of my own OBD2 sensor showing DTC P00AF, indicating turbo actuator or high pressure turbo charger that is specifically detailed in Quality action campaign bulletins issued
The engine code that is always present is a P00AF (turbo boost control “A� module performance, I think over boost) and at one time a P0299 (turbo under boost)
The following warning appeared and code was registered: Check engine light code P00AF Service Electric Throttle Control stop/start unavailable Service stop start system Acceleration issues after shutting down my engine all the codes…

What P00AF means
Source: SAE J2012 / OBD-IIP00AF 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 P00AF
Source: NHTSA files and the OBD-II standardCan I keep driving with P00AF stored?
Nobody can answer that from the code alone, and a site that does is guessing. A steady light generally means the fault was logged and the vehicle is in a reduced-risk mode; a flashing light means stop soon, because a misfiring engine can destroy a catalytic converter in minutes. 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.
