DTC P2111 THROTTLE ACTUATOR CONTROL SYSTEM
– STUCK OPEN
DTC P2112 THROTTLE ACTUATOR CONTROL SYSTEM – STUCK CLOSED
CIRCUIT DESCRIPTION
The throttle actuator is operated by the ECM and it opens and closes the thr\
ottle valve using gears. The
opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttl\
e
body. And, it provides feedback to the ECM to control the throttle actuator \
in order to control the throttle valve
opening angle properly in response to the driving condition. If this malfunctio\
n is detected, the ECM shuts
down the power for the throttle actuator, and the throttle valve is locked at a certain angle by the return spring.
Also, the whole electronically controlled throttle operation is cancelled until th\
e system returns to normal and
the ignition switch is turned to OFF.
HINT:
This ETCS (Electronic Throttle Control System) does not use a throttle\
cable.

WIRING DIAGRAM
Refer to DTC P2102 on page 05–174.
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester II. Freeze frame data record the engine condition\
when
malfunctions are detected. When troubleshooting, freeze frame data can h\
elp determine if the vehicle was
moving or stationary, if the engine was warmed up or not, if the air–fuel ratio was lean \
or rich, and other data
from the time the malfunction occurred.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P2111 AND/OR P2112)
(a) Connect the intelligent tester II to the DLC3.
(b) Turn the ignition switch to ON and turn the intelligent tester II ON.
(c) Select the following menu items: Powertrain / Engine and ECT / DTC.
(d) Read DTCs. Result:

DTC P0606 ECM/PCM PROCESSOR
DTC P0607 CONTROL MODULE PERFORMANCE
DTC P0657 ACTUATOR SUPPLY VOLTAGE
CIRCUIT/OPEN
CIRCUIT DESCRIPTION
The ECM continuously monitors its internal memory status, internal circuits, and output signals to the throttle
actuator. This self–check ensures that the ECM is functioning properly. If any malfunction is detected, the
ECM will set appropriate DTCs and illuminate the MIL.
The ECM memory status is diagnosed by internal ”mirroring” of the main CPU and the sub CPU to detect
Random Access Memory (RAM) errors. The two CPUs also perform continuous mutual monitoring.

INSPECTION PROCEDURE
HINT:
Performing the Intelligent Tester II Active Test allows relay, Vacuum Switching Valve (VSV), actuator and
other items to be operated without removing any parts. Performing the Active Test early in troubleshooting
is one way to shorten labor time. The Data List can be displayed during \
the Active Test.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Intelligent Tester II to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn on the tester.
(f) Clear the DTC.
(g) Select the item ”Enter / Power train / Engine and ECT / Active Test / Control the Shift Position”.
(h) Follow the instructions on the tester and read the Active Test.
HINT:
While driving, the shift position can be forcibly changed with the Intel\
ligent Tester II.
Comparing the shift position commanded by the ACTIVE TEST with the actua\
l shift position enables you
to confirm the problem ( see page 05–241).
