What P050B means
Source: SAE J2012 / OBD-IIP050B 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. The record above is what Nissan and its owners have filed about it; the code’s page across every make has the whole file.
