O2 SENSOR TEST
56 OBD2
„ 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 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.
