About a week ago, the check engine light turned on in the cold morning, I got it checked by a mechanic and scanner code "PO139" Oxygen censor Bank 1/ sensor 2.
Then I went to Autozone and they diagnosed the same problem, so I bought an O2 sensor to replace it my self.
I took out the oxygen censor from the catalytic converter, but couldn't take out the connector from beneath the passenger seat, so I plugged back the O2 sensor as is (without applying any anti seize or anything), thinking to get it changed by a mechanic, but after a couple of days the engine light has gone off on its own.
Now I am not sure what should I do? should I get the O2 censor changed any way ? or should just keep going on ? should I put / apply to the O2 censor that I took out and place again ?
