How much to replace the input and output sensors and connectors?

Thank you for your time. The tech said the computer says it is the input output sensors. So after replacing and it still not working he called Chrysler and was advised that even though the connector looked good they would have to be replaced to rememdy this problem. I will find out this afternoon when I pick it up and if it is still doing the same thing I will have no choice but to take it to a Chrysler dealsership.
