1. On the Diagnostic Tester* screen,
select the following menus:
DIAGNOSTICS
CARB OBD II
O2S TEST RESULTS
A list of the available oxygen sensors
will be displayed.
2. Select the desired oxygen sensor and
press Enter.
NOTE:
The monitor result of the A/F sensor will
not be displayed. If you select
ªBank 1±Sensor 1º or Bank 2±Sensor 1º
for a vehicle equipped with an A/F
sensor, the Diagnostic Tester will
display ªNo parameter to display.º
3. Compare the test results with the
values listed in the Failure
Threshold Chart.
* Although this procedure references the Toyota
Diagnostic Tester, the O2S test results can be
checked using a generic OBDII scantool.
Refer to your OBDII scantool operator's manual
for specific procedures.

NOTE:
Before the O2S Monitor completes or after the ignition switch is turned OFF, the
Diagnostic Tester displays the viewable upper limit or a lower limit of the test value
(example: 0 V, 1.275 V, 0 s [seconds], 10.2 s, 0 and 255).

1. Determine the correct O2S Failure Threshold Chart for your vehicle by looking in the
ªO2S Application Table,º pages 5 ± 9 in this bulletin.
2. Select appropriate year, model, and engine for specified O2S Failure
Threshold Chart.
3. Compare O2S test results with the specified O2S Failure Threshold Chart. It may be
necessary to convert O2S test results to a specific measurement unit using the
conversion factor that is supplied in the specified table. See example below:
Example:
A. The Diagnostic Tester displays
ª17º as a value of the ªTime $81º
(see illustration).
B. Find the Conversion Factor value
of ªTime $81º in the O2S Failure
Threshold chart below.
0.3906 is specified for Time $81
in this chart.
C. Multiply ª17º in step ªAº by 0.3906
(Conversion Factor) in step ªB.º
17 x 0.3906 = 6.6 %
D. If the answer is within the
Standard Value of TEST LIMIT,
the ªTime $81º can be confirmed
to be normal.

NOTE:
ªLOW SW Vº indicates the O2S
voltage when the O2S status changes
from rich to lean.
ªHIGH SW Vº indicates the O2S
voltage when the O2S status changes
from lean to rich.
If the O2S voltage is lower than
ªLOW SW V,º the O2S status is lean.
If the O2S voltage is higher than
ªHIGH SW V,º the O2S status is rich.
