Engine Oil Solenoid Valve Control System Inspection

Connect the M-MDS to the DLC-2.
Perform the KOER self test. (See KOEO/KOER SELF TEST .)
Verify that DTC P06DA:00, P06DB:00, or P06DC:00 are not displayed. (See ON-BOARD DIAGNOSTIC TEST .)
- If DTC P06DA:00, P06DB:00, or P06DC:00 are displayed, perform the DTC inspection. (See DTC P06DA:00 .)
Inspect the engine oil pressure. (See OIL PRESSURE INSPECTION .)
- If the engine oil pressure is not as specified, repair or replace the malfunctioning part according to the inspection results:
Access the following PCM PIDs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .)
- OIL_P_SOL
- RPM
- ECT
With the engine coolant temperature at 98°C {208°F}, increase the engine speed to 4, 000 RPM or higher, and verify that the oil pressure gauge value changes when the data monitor item OIL_P_SOL value is changed from ON to OFF.
- If the oil pressure gauge value change cannot be verified, inspect the engine oil solenoid valve. (Perform the Engine Oil Solenoid Valve Operation Inspection.) (See ENGINE OIL SOLENOID VALVE INSPECTION .)
