Some vehicle may exhibit the CHECK ENGINE light on with DTC P0524 (Engine oil pressure control system: Oil pressure decrease) and no abnormal engine noise. This may be caused by a malfunction of the oil pressure control valve (located at the rear of the engine block near the oil filter) due to machining contamination inside the electromagnet sleeve and the solenoid plunger remaining during manufacturing. This contamination is affecting the OCV operation when oil pressure control is requested by the PCM. REPAIR PROCEDURE Perform the WSM inspection for P0524. |
