Manufacturer summary
Original wording in English
Service Update Bulletin. Certain vehicles may have a condition where the camshaft actuator oil control valve (OCV) center bolt could stick or bind. If this were to happen, it could cause a MIL light to illuminate on the dash (Service Engine Soon), setting diagnostic trouble codes (DTC?s) P0011 or P0014, the engine could run rough and have reduced power. Dealers will inspect for these DTC?s that could have been set by this condition, and repair vehicles that fail the inspection.
