Check engine light

[Viper1980]

I have a 2013 F150 3.5 and my engine light came on and has started making a rattling/knocking sound I guess you could call it. Put it on the scanner and says oxygen sensor. Will that cause the sound that started from out of nowhere?

Is that sound on start up or all the time?

Those are bad sounds.. I'm hopefully wrong, but possibly a bad bearing...

It is all the time.

It is all the time.

My wallet cries for you. That sounds like a spun bearing.

Again, I hope I'm very wrong.
