8 Check wire circuit.
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between “E22-3” terminal of ECM con-
nector and “BLK/YEL” wire terminal of oil control valve con-
nector.
Is resistance
1 Ω
or less?
Go to Step 9. “BLK/YEL” wire
open or high resis-
tance circuit.
9 Check wire circuit.
1) Measure resistance between “E22-3” terminal of ECM con-
nector and vehicle body ground.
Is resistance infinity?
Substitute a know-
good ECM and
recheck.
“BLK/YEL” wire
shorted to ground
