DTC Confirmation Procedure
1) Clear DTC. Refer to DTC Clearance:M13A with VVT .
2) Start engine and keep it at idle for 10 seconds.
3) Check DTC. Refer to DTC Check:M13A with VVT .
DTC Troubleshooting
Step Action YES NO
1
Was “Engine and Emission Control System Check” performed?
Go to Step 2.
2
Oil control valve electrical circuit check
1) Disconnect connectors from ECM with ignition switch turned OFF.
2) Check for proper connection at “E119-2” and “E119-3” terminals of ECM connector.
3) If OK, measure resistance between “E119-2” and “E119-3” terminals of ECM connector.
Is resistance below 10 Ω?
Go to Step 3.
Go to Step 8.
3
Oil control valve electrical circuit check
Was resistance more than 6.5 Ω in Step 2?
Go to Step 4.
Go to Step 7.
4
Oil control valve electrical circuit for power short check
1) Turn ON ignition switch.
2) Measure voltage between “E119-3” terminal of ECM connector and engine ground.
Is voltage below 1 V?
Go to Step 5.
“RED”, “YEL/RED”, “YEL” or “BLK/RED” wire is shorted to power supply circuit.
5
Oil control valve electrical circuit for ground short check
1) Disconnect connector from oil control valve with ignition switch turned OFF.
2) Measure resistance between “E119-3” terminal of ECM connector and engine ground.
Is resistance infinity?
Go to Step 6.
“YEL/RED” wire is shorted to ground circuit.
6
Oil control valve electrical circuit for ground short check
1) Measure resistance between “E119-2” terminal of ECM connector and engine ground.
Is resistance infinity?
Go to Step 9.
“BLK/RED” wire is shorted to ground circuit.
7
Oil control valve electrical circuit for short check
1) Disconnect connector from oil control valve with ignition switch turned OFF.
2) Measure resistance between “E119-3” and “E119-2” terminals of ECM connector.
Is resistance infinity?
Go to Step 9.
“YEL/RED” wire is shorted to “BLK/RED” wire.
8
Oil control valve electrical circuit check
1) Disconnect connector from oil control valve with ignition switch turned OFF.
2) Measure resistance between “E119-3” terminal of ECM connector and “YEL/RED” wire terminal of oil control valve connector and between “E119-2” terminal of ECM connector and “BLK/RED” wire terminal of oil control valve connector.
Is resistance below 1 Ω?
Go to Step 9.
“YEL/RED” wire or “BLK/RED” wire circuit is open or high resistance.
9
Oil control valve check
1) Check oil control valve referring to Oil Control Valve Inspection (For Engine with VVT):M13A .
Is resistance within specified value?
Substitute a known-good ECM and recheck.
Faulty oil control valve.
NOTE:
Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.
