O2 SENSOR TEST
■ X or XX - These characters identify the location of the O2 sensor in
relation to a cylinder bank. An O2 sensor for cylinder bank 1 is iden-
tified by the designation “1” or "B1"; a sensor for cylinder bank 2 is
identified as “2” or "B2."
”Bank One” indicates the side of the engine where cylinder
number one is located (V-type engines). Bank Two is oppo-
site of Bank One.
■ Y orYY - These characters identity the location of the O2 sensor in rela-
tion to the exhaust system catalyst. An O2 sensor located upstream of
the catalyst is identified by the designation”1” or "S1", a sensor located
downstream of the Catalytic Converter is identified as “2” or "S2."
For example, O2S12 or O2SB1S2 is the designation for the down-
stream O2 sensor for cylinder bank 1.
The CanOBD2&1 Scan Tool does not perform O2 sensor
tests, but retrieves results from the most recently performed
O2 sensor tests from the on-board computer's memory. You
may retrieve O2 sensor test results for only one test of one
sensor at any given time.
1. From the "Mode Selection Menu", use
the UP and DOWN buttons, as
necessary, to highlight O2 Sensor Test,
then press the ENTER/LD button.
■ The "Select Sensor" screen displays.
The screen shows all O2 sensors
applicable to the vehicle under test.
If O2 sensor tests are not support-
ed by the vehicle under test, an
advisory message shows on the
CanOBD2&1 Scan Tool's display.
Press the ENTER/LD
button
to return to "Live Data" mode.
2. Use the UP and DOWN but-
tons, as necessary, to highlight the O2
sensor for which you wish to view test
results, then press the ENTER/LD
button.
3. When test results have been retrieved,
results of the first test for the selected
sensor will show on the CanOBD2&1
Scan Tool's display.
4. Use the UP and DOWN but-
tons, as necessary, to view results for
additional tests.
