The engine oil pressure sensor measures the pressure of the oil in the oil rifle on the left-hand side of the engine block.
Possible causes:
1)Mechanical failures such as lubricating oil pump, lubricating oil high pressure relief valve, loose lubricating oil filter2)Breakdown or contamination of lubricating oil3)Plugged lubricating oil filter.
