Follow the procedure “With CONSULT-II” above.
Diagnostic Procedure
EBS00QP0
1.
CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY
1.
Remove the intake air duct.
2.
Check if a foreign matter is caught between the throttle valve
and the housing.
OK or NG
OK
>> GO TO 2.
NG
>> Remove the foreign matter and clean the electric throttle
control actuator inside.
2.
REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
1.
Replace the electric throttle control actuator.
2.
Perform
EC-49, "Throttle Valve Closed Position Learning"
.
3.

DTC P1122 ELECTRIC THROTTLE CONTROL FUNCTION
PFP:16119
Description
EBS00QP2
NOTE:
If DTC P1122 is displayed with DTC P1121 or 1126, first perform the trouble diagnosis for DTC P1121 or
P1126. Refer to
or
.
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 current opening angle of the throttle valve is detected by the throttle position sensor and it provides feed-
back to the ECM to control the throttle control motor to make the throttle valve opening angle properly in
response to driving condition.
On Board Diagnosis Logic
EBS00QP3
This self-diagnosis has the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
DTC Confirmation Procedure
EBS00QP4
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1.
Turn ignition switch “ON” and wait at least 2 seconds.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Start engine and let it idle for 5 seconds.
4.
If DTC is detected, go to
EC-393, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.
DTC No.

Electric throttle control
performance problem
Electric throttle control function does
not operate properly.
●
Harness or connectors
(Throttle control motor circuit is open or shorted.)
●
Harness or connectors
(Throttle control motor relay circuit is open or
shorted.)
●

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
Diagnostic Procedure
