Monitor Description
P052477, P15F009, P15F077 and P15F177:
The ECM monitors the oil pressure based on the signal output from the oil pressure sensor (engine oil pressure and temperature sensor). If it is judged that the actual oil pressure generated by the oil pump assembly is less than the target oil pressure, oil pressure control using the oil pressure control valve assembly is suspended. After a certain period of time has elapsed, if it is judged that the actual oil pressure is low in comparison to the target oil pressure, it is determined that the oil pressure is low and a DTC is stored.
P15F109:
The ECM monitors the oil pressure based on the signal output from the oil pressure sensor (engine oil pressure and temperature sensor). If the oil pressure is less than specified when the piston oil jets are spraying oil (engine speed is 3000 rpm or more), a DTC is stored.
