SOURCE: wont complete scan to pass emission test
When you rest your codes there is a series of tests your ECU has to go through before you can pass emissions. this is done some people can reset the code and go before its sets the code again. on the 96 you can have 2 tests not complete for it to pass. basicly you have to drive the car a couple days for the tests to pass.
check the readiness tests wait until only 2 have not passed. then you should be good.so drive and check.

SOURCE: check engine light on, replaced oxygen sensor before catalyst,
SOURCE: What does the oxygen sensors look like in a 2003
There should be an O2 sensor before and after the catalytic converter on your vehicle, so it will have 2 sensors. You'll need a 7/8" open end wrench or an O2 sensor socket to replace them.
