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.
