Check the following.
• Harness connectors E7, F121
• Harness for open or short between intake valve timing control solenoid valve and IPDM E/R
>> Repair or replace harness or connectors.
3.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN
AND SHORT
1.
Turn ignition switch OFF.

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.

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:0000000001094186
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.
