HI there

The first code, P1389 is for no ASD releay voltage at the pcm

The second code is for a problem with the throttle position sensor. The second code could cause the asd issue if there is a problem with the voltage going to the tps, or the tps itself. I would start by checking the tps and the tps circuit, then if the asd problem continues, try a new ads relay.
