P0137

Showing the 60 model years where P0137 appears most; it is on file for 82 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.

Owners’ 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.

Service bulletins and campaigns whose filed summary names P0137. Quoting the document number at a service desk is often the fastest route to a diagnosis someone has already written down.

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.
