INSPECTION PROCEDURE
HINT:
Read freeze frame data usingthe 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.

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.
