Q: The check engine light is on. P0158 code!

asked by on

AutoZone gave a report which defined the P0158 code. It says that the Bank 2, Sensor 2 O2 electrical circuit signal had high voltage for a predetermined period of time. The error codes read are P0158, P0157 and P0159. Firstly, I want to know whether it is a major issue or minor? What problems would arise if it is not fixed? And how much would it cost to get it fixed?

My car has 126000 miles.
My car has an automatic transmission.
