#2006 CHEVY COBALT OXYGEN SENSOR HOW TO#
I am NOT a mechanic and I am just learning how to work on cars so any help will be appreciated I just find it odd that the original o2 sensor was behind the converter but everything that I find online shows that it goes before the converter. I guess what I am asking is where does the o2 sensor on my car truly belong? Does it go before the converter or after it? I can plug the other hole using a spark plug or something like that. If this was the case, why was the o2 sensor after the converter on the original one we replaced? I looked online for a new sensor and everything I have found shows that the sensor goes into the hole before the converter. The check engine light came on a few hours after replacing the converter. But I think we may have damaged the o2 sensor during changing. One in the same place as the old one, and then one before the actual converter up near the flex pipe. New converter I installed has 2 holes for sensors. It was between the converter and the exhaust pipe. When I took off the old converter, the oxygen sensor was behind the converter. I had to replace the catalytic converter on my 2006 Chevrolet Cobalt.
