I replace o2 sensor bank one

Question

replace bank one sensor sensor on check light still comes on any other ideas what it could be?

Answer 1

oxygen sensor replaced. depending on the code that is set, you can replace a 02 sensor due to a 02 sensor being a slow response, and set another code for a different situation, unless the code is known the solution can not be resolved, you need the trouble code to see what the ECM see and this will point in the right direction
