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 P06DB:00 or P06DC:00 is not displayed. (See ON-BOARD DIAGNOSTIC TEST .)
- If DTC P06DB:00 or P06DC:00 is displayed, perform the DTC inspection. (See DTC P06DB:00 .) (See DTC P06DC: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 .)
