Showing the 60 model years where P050D appears most; it is on file for 270 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.
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.
The vehicle was towed to the local dealer, where it was diagnosed, and DTC: P0300, P050D, and P0302 were retrieved
I immediately took the vehicle to the local mechanic who identified two codes (P0300 and P050D) related to the engine issues
The contact declined the repair, and the vehicle was taken to an independent mechanic, where it was diagnosed with codes: P050D, P2099, P219B, and P0300 for the fuel injector
I have it hooked up to the diagnostics machine and get P050D code as well as one more code (don't remember that one)
This is the second time this same exact thing has happened to me same messages popped up so I took it to the dealer and codes p0300 came out and p050D came out

What P050D means
Source: SAE J2012 / OBD-IIP050D 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 P050D
Source: NHTSA files and the OBD-II standardCan I keep driving with P050D 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.
