Would the o2 sensor cause the ses light to come on. The mechanic reset the codes so if it comes back it must be the o2 sensor,.

the O2 if bad will set the light off again however just cause the light comes back ondoes not neccisarily mean that it is the O2 sensor it may be something else you will need it checked again to get the proper diagnosis

If you still have the original O2, it'* a good idea to change it. It'* a $45 part.

A bad O2 sensor, dirty MAF sensor, bad Throttle position sensor, bad plugs/wires, weak coils.

With the mileage you have on that car, replacing it is a good idea. Just make sure it'* not a Bosh O2 sensor, they don't seem to last long in our cars.

The code also said could possibly be a bad catalatic converter, since the old one was changed before I bought it, and the mechanic said it had a small leak in it, and he also said it was the worst sodering job he has every seen on one of those. So I might be looking at a new cataltic converter also if the light comes back on.
