Only problem with this is that an o2 sensor code can be thrown by more than a bad o2 sensor. That could indicate an emissions vaccum leak as well. Cel codes are only a basis to begin diagnostic. That's why so many people get pissed off at autozoners when they buy part after a code reading and it doesn't fix the problem
