I got a check engine light due to my o2 sensor. It says bank 2 i was woundering which side is that?

 

Passenger side

 

Is it hard to do? Or is it a simple disconnet

 

Is what hard to do? Replacing the sensor? You'll be able to see it once you remove all the fasteners on the plastic cover under the engine. I never replaced or played around with mine, I took it to a shop. It's much easier for them to do it while it's on a lift.

 

true ok sounds good. i will take it to my mechanic. thanks alot
