This is a good tip. I picked up my F-150 from a dealer after a power cut out problem. Every warning light would come on. They said I needed a new accelerator. $500. They drove it and said it was fixed. I didn’t get a half mile from the place and the problem recurred.

Electrical problems are notoriously difficult to diagnose and fix. Many sensors share the same power cable so it's not unheard of to misdiagnose a sensor.

I know. I formerly owned an aircraft maintenance business. This dealer didn’t do much in!the way of diagnosis. Of course the errors reset so it took a little driving for them to act up and the problem to recur. I took it to another dealer that found a wire bundle chafing. If I had continued with the first dealer it would have been more parts swapping. Related to the OP it is advisable to do a good shake down run immediately.

You're spot on. Also its not uncommon for a problem to hid behind another code. So you fix the first code, think its good and then the real code pops up.
