DTC P2 111 THROTTLE ACTUATOR CONTROL SYSTEM
− STUCK OPEN
DTC P2 11 2 THROTTLE ACTUATOR CONTROL SYSTEM
− STUCK CLOSED
CIRCUIT DESCRIPTION
The throttle motor is operated by the ECM and it opens and closes the throttle valve using gears. The open-
ing angle of the throttle valve is detected by the throttle position sensor, which is mounted on the throttle body.
The throttle position sensor provides feedback to the ECM to control the throttle motor and set the throttle
valve angle in response to driver input.
HINT:
This Electrical Throttle Control System (ETCS) does not use a throttle cable.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand−held tester . Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, 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 INSPECT THROTTLE BODY ASSY(VISUALLY CHECK THROTTLE VALVE)
(a) Check if a foreign object has been caught between the throttle valve and the housing.

DTC P2103 THROTTLE ACTUATOR CONTROL MOTOR
CIRCUIT HIGH
CIRCUIT DESCRIPTION
The throttle motor is operated by the ECM and it opens and closes the throttle valve.
The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the
throttle body. The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to
control the throttle motor and monitor the throttle opening angle as the ECM responds to driver input.
HINT:
This Electrical Throttle Control System (ETCS) does not use a throttle cable.

DATA LIST/ACTIVE TEST
1. DATA LIST
HINT:
Using the hand−held tester DATA LIST allows switch, sensor, actuator and other item values to be read with-
out removing any parts. Reading DATA LIST early in troubleshooting is one way to shorten labor time.
NOTICE:
In the table below, the values listed under ”Normal Condition” are reference values. Do not depend
solely on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch to OFF.
(c) Connect the hand−held tester to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the hand−held tester ON.
(f) Enter the following menus: DIAGNOSIS / OBD/MOBD / DATA LIST.
(g) According to the display on the tester, read DATA LIST.

2. ACTIVE TEST
HINT:
Performing ACTIVE TEST using the hand−held tester allows the relay, VSV, actuator and so on to operate
without parts removal. Performing ACTIVE TEST as a first step of troubleshooting is one of the methods to
shorten diagnostic time.
It is possible to display DATA LIST during ACTIVE TEST.
(a) Turn the ignition switch to OFF.
(b) Connect the hand−held tester to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the hand−held tester ON.
(e) Enter the following menus: DIAGNOSIS / OBD/MOBD / ACTIVE TEST.
(f) According to the display on the tester, perform ACTIVE TEST.

The ECM opens and closes the intake shutter valve (throttle valve) using the rotary solenoid type actuator.
Upon opening and closing the valve, the exhaust gas recirculation volume is properly controlled. Also, en-
gine vibration and noise will be reduced by closing the valve when the engine is stopped.
