P1111 IVT CONTROL SOLENOID VALVE

P1111 IVT CONTROL SOLENOID VALVE

Description

INFOID:0000000001161851

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.

ness connector.

4.

Also check harness for short to ground and short to power. 

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

4.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE

Refer to 

EC-883, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace intake valve timing control solenoid valve.

1.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I

1.

Turn ignition switch OFF.

2.

Disconnect intake valve timing control solenoid valve harness connector.

3.

Check resistance between intake valve timing control solenoid valve terminals as follows.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace intake valve timing control solenoid valve.

2.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II

1.

2.

Provide 12V 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 12V 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.

P1121 ELECTRIC THROTTLE CONTROL ACTUATOR

Description

INFOID:0000000001161855

Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The throttle position sensor detects the throttle valve position, and the opening and closing speed of the throt-
tle valve and feeds the voltage signals to the ECM. The ECM judges the current opening angle of the throttle
valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening
angle properly in response to driving condition.
