NOTES OXYGEN SENSOR TEST RESULTS
The oxygen sensor tests refer to the post catalyst that are
installed on EEC-V vehicles to provide additional feedback
concerning the functioning of the emissions system.
As seen below, selecting the OXYGEN SENSOR TESTS
function from the generic OBD II menu displays a list of oxygen
sensor tests to conduct.
Choosing one of the oxygen sensor tests and pressing the
TRIGGER displays a screen that provides oxygen sensor test
results. The test results are from the most recent monitoring of
the oxygen sensors during an OBD II drive cycle. Test results
will be updated each time a monitoring session occurs.
