DTC P1121 ELECTRIC THROTTLE CONTROL ACTUATOR

DTC P1121 ELECTRIC THROTTLE CONTROL ACTUATORPFP:16119
Component DescriptionBBS0051X
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 throttle position sensor detects the throttle valve position, and the opening and closing speed of the throt-
tle valve and feeds the voltage signals to the ECM. The ECM judges the current opening angle of the throttle
valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening
angle properly in response to driving condition.
On Board Diagnosis LogicBBS0051Y
These self-diagnoses have the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, ECM enters fail-safe mode and the MI lights up.
DTC Confirmation ProcedureBBS0051Z
NOTE:

Perform PROCEDURE FOR MALFUNCTION A AND B first. If the 1st trip DTC cannot be confirmed,
perform PROCEDURE FOR MALFUNCTION C.

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait
at least 10 seconds before conducting the next test.
PROCEDURE FOR MALFUNCTION A AND B
With CONSULT-II
1. Turn ignition switch ON and wait at least 1 second.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Shift selector lever to D position and wait at least 2 seconds.
4. Shift selector lever to P or N position.
5. Turn ignition switch OFF and wait at least 10 seconds.
6. Turn ignition switch ON and wait at least 1 second.
7. Shift selector lever to D position and wait at least 2 seconds.
8. Shift selector lever to P or N position.
9. Turn ignition switch OFF, wait at least 10 seconds and then turn
ON.
10. If 1st trip DTC is detected, go to EC-553, "
Diagnostic Procedure"
.
Without CONSULT-II
1. Turn ignition switch ON and wait at least 1 second.
2. Shift selector lever to D position and wait at least 2 seconds.
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
P1121
1121Electric throttle control
actuatorA)Electric throttle control actuator does not func-
tion properly due to the return spring malfunc-
tion.

Electric throttle control actuator
B)Throttle valve opening angle in fail-safe mode is
not in specified range.
C) ECM detect the throttle valve is stuck open.
Detected items Engine operating condition in fail-safe mode
Malfunction AThe ECM controls the electric throttle actuator by regulating the throttle opening around the idle position.
The engine speed will not rise more than 2,000 rpm.
Malfunction B ECM controls the electric throttle control actuator by regulating the throttle opening to 20 degrees or less.
Malfunction CWhile the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops, the engine stalls.
The engine can restart in P or N position, and engine speed will not exceed 1,000 rpm or more.

10. If 1st trip DTC is detected, go to EC-553, "
Diagnostic Procedure" .
PROCEDURE FOR MALFUNCTION C
With CONSULT-II
1. Turn ignition switch ON and wait at least 1 second.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Shift selector lever to D position and wait at least 2 seconds.
4. Shift selector lever to P or N position.
5. Start engine and let it idle for 3 seconds.
6. If DTC is detected, go to EC-553, "
Diagnostic Procedure" .
Without CONSULT-II
1. Turn ignition switch ON and wait at least 1 second.
2. Shift selector lever to D position and wait at least 2 seconds.
3. Shift selector lever to P or N position.

5. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
6. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
7. If DTC is detected, go to EC-553, "
Diagnostic Procedure" .
Diagnostic ProcedureBBS00520
1. CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY
1. Turn ignition switch OFF.
2. Remove the intake air duct.
3. 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.

DTC Confirmation ProcedureBBS0053P
CAUTION:
Always drive vehicle at a safe speed.
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.

Procedure for malfunction B is not described here. It takes extremely long time to complete procedure for
malfunction B. By performing procedure for malfunction A, the incident that causes malfunction B can be
detected.
WITH CONSULT-II
TESTING CONDITION:
Steps 4 and 5 may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
1. Start engine.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Press CRUISE switch and make sure that CRUISE indicator
lights up.
4. Drive the vehicle for at least 5 consecutive seconds under the
following condition.
If 1st trip DTC is detected, go to EC-606, "
Diagnostic Procedure"
.
If 1st trip DTC is not detected, go to the following step.
5. Drive the vehicle for at least 5 consecutive seconds under the following condition.
6. If 1st trip DTC is detected, go to EC-606, "
Diagnostic Procedure" .
