DTC P1128 THROTTLE CONTROL MOTOR
PFP:16119
Component Description
EBS00QZX
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
EBS00QZY
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
EBS00QZZ
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-777, "Diagnostic Procedure"
.
WITHOUT CONSULT-II
1.
Turn ignition switch “ON” and wait at least 2 second.
2.
Start engine and let it idle for 5 seconds.
3.
Turn ignition switch “OFF”, wait at least 10 seconds and then turn “ON”.
4.
Perform “Diagnostic Test Mode II (Self-diagnostic results)” with ECM.
5.
If DTC is detected, go to
EC-777, "Diagnostic Procedure"
.
DTC No.

1128
Throttle control motor
circuit short
ECM detects short 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.

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
EBS00R01
1.
RETIGHTEN GROUND SCREWS
1.
Turn ignition switch “OFF”.
2.
Loosen and retighten engine ground screws.
