There is more than one oxygen sensor. You will need to test them all no matter which one the code is pinpointing to be at fault. If all sensors are OK, flow test the catalytic converter. A clogged/faulty converter will also throw an O2 sensor code..

Test all oxygen sensors, not only the one indicated by the code. If every sensor tests OK, flow-test the catalytic converter, because a clogged or faulty converter can also set an O2 sensor code.
Conversation Summary
The owner of a 1913 Saturn reports code 13 and an oxygen sensor voltage that stays around 0.800-0.878 and does not drop to 0.300. Replacing the O2 sensor did not turn off the check engine light. The expert advises testing every oxygen sensor regardless of which one the code points to, then flow-testing the catalytic converter if the sensors are OK.
