P0122 AND P01635

What is your question?

I have two recurring DTCs (P0122 and P01635); they are pending and hard. I checked the wiring to the throttle position sensor and the PCM with a voltmeter. They checked good. I replaced the TPS (and the IAC because I was there) and have tried deleting the codes (w/ code reader, battery disconnect, fuse pulls, and PCM disconnect at battery). They will not delete. I also have a bad fuel level sending unit. It will ring that I am low on fuel after a 23 gallon fill up and randomly thereafter. Can a bad fuel level sending unit set the P0122 and P01635 DTCs?
