DTC P1128 THROTTLE CONTROL MOTOR
DTC P1128 THROTTLE CONTROL MOTOR
PFP:16119
Component Description
EBS00QPG
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
EBS00QPH
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
EBS00QPI
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-406, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.
DTC No.
Trouble diagnosis name
DTC detecting condition
Possible cause
P1128
1128
Throttle control motor
circuit short
ECM detects short in both circuits between
ECM and throttle control motor.
●
Harness or connectors
(Throttle control motor circuit is shorted.)
●
Electric throttle control actuator
(Throttle control motor)
Engine operating condition in fail-safe mode
ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return
spring.
