Welcome to the forum Walt,
Good to have you with us.
Follow Grahams advice. The original codes were most likely an air leak the sensors were just showing the fault. You need to check that you have fitted the correct sensors and all the connections are good.
If you haven't done so already you should add your car details to your signature to help others to help you.

I have a "restricted performance" alarm and stopped into the local dealership. Told me I had a cracked plastic air intake valve and it was causing a lean mix. $125 to tell me that, and $485 to order the plastic intake valve and install it. Did I just get duped? (First time on the forum and this is the only place "search" led me)
