DIAGNOSTICS SFI SYSTEM (1ZZ–FE/3ZZ–FE)(From February, 2004)
AVENSIS REPAIR MANUAL SUPPLEMENT
(RM1098E)
DTC P0171 SYSTEM TOO LEAN (BANK 1)
DTC P0172 SYSTEM TOO RICH (BANK 1)
CIRCUIT DESCRIPTION
The fuel trim is related to the feedback compensation value, not to the bas\
ic injection time. The fuel trim in-
cludes the short–term fuel trim and the long–term fuel trim.
The short–term fuel trim is the short–term fuel compensation used to \
maintain the air–fuel ratio at its ideal
theoretical value. The signal from the heated oxygen sensor indicates whether the air–fuel r\
atio is rich or
lean compared to the ideal theoretical value, triggering a reduction in the \
fuel volume if the air–fuel ratio is
rich, and an increase in the fuel volume if it is lean.
The long–term fuel trim is the overall fuel compensation in order to bal\
ance the short–term fuel trim for a
continual deviation from the central value by individual engine differences, operating environment and age
deterioration.
If both the short–term fuel trim and the long–term fuel trim are l\
ean or rich beyond a standard level, it is de-
tected as a malfunction in the SFI system. The ECM illuminates the MIL and the\
DTC is set.

HINT:
When DTC P0171 is set, the actual air–fuel ratio is lean. When DTC P0172 is set, the actual air–fuel\

ratio is rich.
If the vehicle runs out of fuel, the air–fuel ratio is lean and DTC P01\
71 may be set. The MIL then illumi-
nates.
If the total of the short–term fuel trim value and long–term fuel trim value is within
20 %, the system
is functioning normally.

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.

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:

HINT:
If any DTCs other than P2111 or P2112 are output, troubleshoot those DTCs first.
