DTC CONFIRMATION PROCEDURE
NOTE:
Check to make sure that the following conditions are satisfied when using this DTC CONFIRMATION
PROCEDURE.
• Intake air temperature: –7°C (19.4°F) or higher
• Engine coolant temperature: –7°C (19.4°F) or higher
• Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
1) Clear DTC. Refer to "Diagnostic Trouble Code (DTC) Clearance".
2) Start engine.
3) Maintain engine speed at 2000 r/min. or higher for 5 seconds.

TROUBLESHOOTING
Step
1 Was "Engine and Emission Control System Check" per-
formed?
2 Check oil control valve power supply circuit.
1) Turn OFF ignition switch, disconnect connector from oil
control valve.
2) Turn ignition switch ON, measure voltage between "BLK/
RED" wire terminal of oil control valve connector and
engine ground.
Is voltage 10 – 14 V?
3 Check wire circuit.
1) Turn OFF ignition switch, disconnect connectors from
ECM.
2) Check for proper connection to "C63-2" wire terminal of
ECM connector.
3) If OK, measure resistance between "C63-2" wire terminal
of ECM connector and vehicle body ground.
Is resistance infinity?
4 Check wire circuit.
1) Turn ignition switch ON, measure voltage between "C63-2"
wire terminal of ECM connector and engine ground.
Is voltage 0 V?
5 Check wire circuit.
1) Turn OFF ignition switch, connect connector to oil control
valve.
2) Turn ignition switch ON, measure voltage between "C63-2"
wire terminal of ECM connector and engine ground.
Is voltage 10 – 14 V?
6 Check oil control valve.
1) Check oil control valve referring to "Oil control valve
inspection" in Section 6E1.
Is it in good condition?
Action Yes
Go to Step 2. Go to "Engine and
Emission Control
System Check" in
this section.
Go to Step 3. "BLK/RED" wire
open circuit.
Go to Step 4. "BLU" wire shorted
to ground circuit.
Go to Step 5. "BLU" wire shorted
to power supply
circuit.
Go to Step 6. "BLU" wire open
circuit.
Go to Step 7. Replace oil con-
trol valve.
No
