Also check harness for short to ground and to power.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Repair or replace malfunctioning part.

6.

CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY

1.

Remove the intake air duct. Refer to 

EM-31, "Removal and Installation"

.

2.

Check if foreign matter is caught between the throttle valve and the housing.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Remove the foreign matter and clean the electric throttle control actuator inside, then perform

throttle valve closed position learning. Refer to 

EC-145, "Work Procedure"

.

7.

CHECK THROTTLE CONTROL MOTOR

Check the throttle control motor. Refer to 

EC-366, "Component Inspection"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace electric throttle control actuator. Refer to 

EM-33, "Removal and Installation"

.

Component Inspection

DTC Description

INFOID:0000000010775261

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (Throttle control motor circuit is shorted.)
• Electric throttle control actuator (Throttle control motor)

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
