2002 saturn sl1 265,000 miles A/T- TP code P0122 circuit low input

I have had this issue for years I buy a new throttle position sensor and it starts acting up after usually 500 miles or so...just one question....does anybody know how to solve this problem it puts alot of stress on my transmission constantly reving up all the time...little info, it does it worse when it's hot outside but it still will act up in cold just not as often and not as bad, also if I unplug the sensor let it sit for couple hours it will drive normal after I plug it in ....it use to last about two weeks with no problems after plugging it back in but now after plugging back in I'm lucky to get one 8 mile trip home from work before it acts up.....I know after market tps aren't great I've tries ...duralast twice,then walker twice.....I saw I think it's called senco tps but 80 bucks if it's known to work then I'll get it ...thanks in advance for help.
