Where P0204 shows up
Source: NHTSA manufacturer communications and complaintsShowing the 25 model years where P0204 appears most; it is on file for 26 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.

P0204 by make
The same record, one make at a time: the model years, bulletins and owner reports that name P0204 on that maker’s vehicles.

What owners said

After their analysis here is their statement on the service invoice: "Client state check engine light comes on and vehicle will run rough - Client scan for codes and had codes P0202 & P0204
Engine codes P0544, P244D, P242D & P242C were listed stating "exhaust gas temp sensor" and "exhaust temp high for DPF" along with code P0204 "number 4 fuel injector circuit open"
136 manufacturer filings name P0204. 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.

What P0204 means
Source: SAE J2012 / OBD-IIP0204 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 P0204
Source: NHTSA files and the OBD-II standardCan I keep driving with P0204 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.
