This is caused by a drop in engine oil pressure due to a piece of foreign object stuck on the oil pump
pressure relief valve or oil control valve (OCV). The temporary entry of the foreign object triggers a check
engine light on, but rough idle will not be produced until a later time.
Customers having this concern should have their vehicle repaired using the following flow charts and repair
procedure.
