Diagnosis Procedure

INFOID:0000000011278156

1.

CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY 

1. Remove the intake air duct. Refer to 

EM-26, "Exploded View"

.

DTC No.

A

Electric throttle control actuator does not function properly due to the 
return spring malfunction.

B

2. Check if foreign matter is caught between the throttle valve and the housing.
Is the inspection result normal?

YES

>> Replace electric throttle control actuator. Refer to 

EM-29, "Removal and Installation"

.

NO

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

DTC Description

INFOID:0000000011278157

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (APP sensor 1 circuit is open or shorted.)

• Accelerator pedal position sensor (APP sensor 1)

FAIL-SAFE

• The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle

position to be within +10 degrees.

• The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. So, the

acceleration will be poor.

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P2122 or P2123 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

EC-382, "DTC Description"

.

NO

>> GO TO 2.

2.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is more than 8 V at idle.

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start engine and let it idle for 1 second.

2. Check DTC.
