Are o2 sensors related to catalytic converter problems?

What is your question?

The car ran for two days, no problem. The third day it quit. We were told that coils needed to be replaced. Waiting to have a compression tester to test it. Could this be related to an o2 sensor also?

What makes this problem better or worse?

It wont crank at all

How long has your 2007 Kia Rio had this problem?

A few weeks.

*Professional* hands-on diagnosis IS required! ALL Ignition coils do not fail at same time - 02 sensor is not the culprit.

02 sensor readings will reveal a failed catalytic converter but thatâ€™s the only relation.

If it won't crank it has nothing to do with the o2 sensors or coils. You've gotta figure out why the starter isn't running first.

And you won't be able to do a compression test if the motor isnt cranking either.
