Hi welcome to will answer your question the best I can,
Getting the code does not necessarily mean you have to replace the A/F sensors but to check there operation first ,

OK , Now we know for certain that the A/F sensors are ok.(there new)
So it looks like we have a circuit problem or a bad ECM
below is a test diagram for you to check where the problem is.

If you think you are not the Car DIY type then you can take this to your local Garage and give him a head start on the repair. also showing him you know whats up with your car.
