My tps sweeps all the way to 8k ohms, I'm assuming it needs to be replaced.If i get get a new one would i need to adjust it? i haven't really driven the car yet so i don't know how bad its gonna hesitate but it hunts at around 8-1k rpm when the car warms up.

 

Yes it will need to be adjusted

 

i just replaced my tps and it got rid of my hunting idle

 

Did you get a new one or a used one? How reliable or how long do these tps last for and why do they go out?

 

i got a used one..i dont know how long they last but they are cheap if you need to buy one here on the forum

 

new's about 360 from mazdatrix, FWIW

If it sweeps all the way to 8 kohms, then yea, you definitely need to replace it. I'm assuming you have a S4 TPS?

 

Yeah its a s4 tps, anyone know why they go out or how long they should last?

 

let's see.......your car is 20 years old? The sensor's probably a stock one, it's bound to go out sometime. I think there were some places selling the OEM TPS for cheap....might want to try to find these threads on the forum.
