Inspect the fuses for circuits related to this system before performing the following procedure.
When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
CHECK ENGINE OIL LEVEL
Check the engine oil level.

PERFORM ENGINE OIL PRESSURE CONTROL SYSTEM CHECK
Disconnect the connector of the oil pressure switching valve assembly.
Make sure that the engine is stopped before disconnecting the connector of the oil pressure switching valve assembly.
Make sure that the disconnected connector does not get caught in moving engine parts.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Start the engine and warm it up.

Low oil pressure control mode is not performed when the connector of the oil pressure switching valve assembly is disconnected. Therefore, if the measurement results from Engine Oil Pressure Control Check all indicate oil pressure values which are high, it can be determined that there is an electrical malfunction.

REPAIR OR REPLACE OIL PUMP ASSEMBLY (OIL PUMP DRIVE AND DRIVEN ROTOR)
Repair or replace the oil pump assembly (oil pump drive and driven rotor).
If the oil pressure does not rise after disconnecting the connector of the oil pressure switching valve assembly, or if the oil pressure changes, but the difference between the low oil pressure and high oil pressure is small, a mechanical malfunction is probably the cause.
The sleeve is stuck due to foreign matter.
The oil pressure relief valve is stuck due to foreign matter.
The check valve is stuck.
