P30BF on Chevrolet vehicles

A model year is listed because the code is named in its own record — a bulletin filed against it, or an owner’s complaint about it — not because every one of these vehicles sets it. Counts are documents in NHTSA’s files, not failure rates.

Bulletins and campaigns Chevrolet filed with NHTSA whose summary names P30BF. Quote the document number at the service desk — it is a diagnosis the maker has already written down.

A stored code names the test that failed, never the part that caused it. The record above is what Chevrolet and its owners have filed about it; the code’s page across every make has the whole file.
