It should throw a code but not always as most codes are a timed event. I'd still do a sweep on the voltage from idle to wfo and see if it's a smooth transition with no drop outs. You can probe the TPS itself or the ECM wire terminal for that signal wire. Only takes a minute.Ron.
I am sorry. In text under you advise me to check voltage TPS. And I ask you for a reason because I thought that about wrong voltage inform codes.
