Refer to DTC P0335 and P0339 on page 05–136.
INSPECTION PROCEDURE
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 VALVE TIMING(CHECK FOR LOOSENESS AND JUMPED TEETH ON
TIMING CHAIN) (See page 14–49 of Pub. No. RM1018E AVENSIS)
(a) Check for looseness or a jumped tooth of the timing chain.
OK: The matchmarks of the crankshaft pulley and camshaft pulley are alig\
ned.

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.
