How much off hand do you think it will cost for everything like labor, replacement all.
Can I still drive for how long.

Answer 1

P2270 Lack of H02S Bank 1 Sensor 2 switch , Sensor indicates lean

This is safe to drive, what you should do is clear the code and go ahead and drive the vehicle, as you drive the vehicle , you can consider this a test for the H02S sensor. As for the cost it depends on what causes the system to go lean, exhaust leak just prior to the H02S sensor can cause this code condition. a faulty H02S sensor can cause this , depending on what the cause is will determine the cost.
