Additional OBD2 Tests
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
identified 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 opposite
of Bank One.
� Y or YY - These characters identity the location of the O2 sensor in
relation 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
downstream 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.
