Showing the 25 model years where P2111 appears most; it is on file for 39 in total.
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.

P2111 by make
The same record, one make at a time: the model years, bulletins and owner reports that name P2111 on that maker’s vehicles.
What it gets filed under
When owners report it
miles, typically
Half of the 14 owner reports naming P2111 that carry an odometer reading fall between 6,000 and 66,000 miles. A code that shows up at 30,000 miles is a different proposition from one that shows up at 130,000, and that difference is the single most useful thing in this record.
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.
Then my engine light went on and i had to have it towed to the nearest mechanic and when they checked the car had 4 codes P0123 P0222 P2111 and U0420
Check engine light comes on and goes off randomly throwing code P2111 for throttle body being stuck open
Took vehicle to autozone for diagnostic scan and yes, the error code P2111 "throttle body actuator control system,stuck open" is what was read
The vehicle was taken to an independent mechanic who retrieved diagnostic trouble code: P2111 (throttle actuator control system stuck open)

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.

What P2111 means
Source: SAE J2012 / OBD-IIThe electronic throttle is stuck open.
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 P2111
Source: NHTSA files and the OBD-II standardCan I keep driving with P2111 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.
