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.

 

Low circuit input sounds like you have an issue with the 5 volt signal getting to the sensor. Maybe partially shorting giving less than five volts or shorting out and giving your 0V as the reference, both of which will throw a code.

If the only thing that seems to fix it is switching sensors, and that is working for less and less time, I'm thinking the issue is actually the connector, either where it makes contact with a sensor or where it goes through it's protective cover. I would replace that pigtail on the sensor before blowing any more money on sensors.
