4. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand±held tester allows you to operate the relay, VSV, actuator,
etc. without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one way to
shorten the labor time. It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) According to the display on the tester, perform the ACTIVE TEST.

DTCP2111THROTTLE ACTUATOR CONTROL SYSTEM
± STUCK OPEN
DTCP2112THROTTLE 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.
And, it provides feedback to the ECM to control the throttle motor in order \
to make the throttle valve opening
angle properly in response to the driving condition. If this malfunction is d\
etected, the ECM shuts down the
power for the throttle motor, and the throttle valve is closed by the return spring. And the throttl\
e valve is
locked at a certain opening angle. Also, the whole electronically controlled t\
hrottle operation is cancelled until
the system returns to normal and the ignition switch is turned OFF.
HINT:
This electrical throttle system is no used 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, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1 INSPECT THROTTLE BODY ASSY(VISUALLY CHECK THROTTLE VALVE)

housing.

DTC P2118 THROTTLE ACTUATOR CONTROL MOTOR
CURRENT RANGE/PERFORMANCE
CIRCUIT DESCRIPTION
The Electronic Throttle Control System (ETCS) has a dedicated power supply circuit. The voltage (+BM) is
monitored and when the voltage is low (less than 4V), the ECM concludes that the ETCS has a fault and
current to the throttle control motor is cut.
When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage
is low, the current to the motor is cut. If repairs are made and the system has returned to normal, turn the
ignition switch to OFF. The ECM then allows current to flow to the motor and the motor can be restarted.
HINT:
This Electrical Throttle Control System (ETCS) does not use a throttle cable.
