O2S TEST RESULT
INTRODUCTION
The O2S TEST RESULT refers to the results of the engine con-
trol module (ECM) when it monitors the oxygen sensor (O2S),
and it can be read using the hand-held tester or the generic
OBD II scan tool. Based on this, you can find the O2S's condi-
tions.
The ECM monitors the O2S in the various items. You can read
the monitor result (TEST DATA) of each monitor item using the
O2S TEST RESULT. However, the output value of the TEST
DATA is the latest "snapshot" value that is taken after monitor-
ing and therefore it is not dynamic.
In this repair manual, the description of the O2S TEST RESULT
(for O2S related DTCs) are written in a table.
This table consists of 5 items:
(1) TEST ID (a code applied to each TEST DATA)
(2) Description of TEST DATA
(3) Conversion Factor (When Conversion Factor has a
value written in the table, multiply the TEST DATA
value appearing on the scan tool by the Conversion
Factor value. The result will be the required value.)
(4) Unit
(5) Standard Value
If the TEST DATA value appearing on the scan tool is out of the
standard value, the O2S is malfunctioning. If it is within the stan-
dard value, the O2S is functioning normally. However, if the val-
ue is on the borderline of the standard value, the O2S may mal-
function very soon.
HOW TO READ O2S TEST RESULT USING HAND-HELD
TESTER
(a) Connect the hand-held tester to the DLC3.
(b) On the tester screen, select the following menus: DIAG-

A21191 the O2S TEST RESULT chart below. 0.3906 is spe-
cified for $81 in this chart.
(3) Multiply "17" in step (1) by 0.3906 (Conversion Fac-
tor) in the step (2).
17 x 0.3906 = 6.6 %
(4) If the answer is within the standard value, the "TIME
$81" can be confirmed to be normal.
