Hello and welcome to JustAnswer!

If the sensors were replaced and you're setting sensor circuit codes then yes, it's going to be a wiring or engine controller issue. A wiring issue is much more likely. Replacing the entire wiring harness would be quite expensive if it's still available, it's more common to locate and repair the actual failure.

What P codes are setting?
