2. Provide 12 V DC between intake valve timing control solenoid
valve terminals 1 and 2, and then interrupt it. Make sure that the
plunger moves as shown in the figure.
CAUTION:
Do not apply 12 V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve
timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control
solenoid valve is removed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace intake valve timing control solenoid valve. Refer to EM-59, "

P0075 IVT CONTROL SOLENOID VALVE
P0075 IVT CONTROL SOLENOID VALVE
DescriptionINFOID:0000000005929828
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.
