Did these codes Just start after you replaced the starter? If so, did you hook everything up and in the correct locations? All transmission harnesses hooked up? Did you Unhook battery before replacing starter? Did you hook up battery correctly and in the correct order?

Go to this site and search your trouble code. https://www.obd-codes.com/ I'm pretty sure you'll find the problem is in the wiring somewhere since it started after you'd been working on it. One of the connections is likely not tight or perhaps a wire itself got damaged during removal or replacement. I would double check all that first.
