I have a 1998 Jeep Wrangler TJ with 2.5 L engine. I have had the Throttle Position Sensor (TPS) replaced twice. i now have a check engine light on again with the same signs of a bad TPS stuttering going up hills etc... The last time it was replaced it had water in it. I was wondering what might let water in there? Vacuum Leak? I'm not sure.
Any help would be great

It's rare for moisture to get in from the intake path. The shaft is sealed quite well. The Wrangler is quite open underneath, is it possible that water entered the engine compartment from the street? Do you drive offroad? These are pretty obvious, so I will assume that this was already considered. Was the moisture in the sensor coolant (green) or water? If coolant, there may be a leak in the throttle body as I recall, it is warmed by coolant. Sorry I couldn't be more help. Good Luck.

Chris, you could check it with a volt meter. You should be able to find information online on how to measure it. Make sure you have the gasket on for the TPS. Check your connector for any corrosion. Try this with a COLD engine to find any vacuum leaks, with the engine running take a can of starter fluid and spray your vacuum lines. Spray your cold air intake also. If your idle increases then you have a vacuum leak. Find it and fix it. This always works for me.

check the mas sensor the tiny hole inside the opening gets carbon in it spay electronic cleaner in it. repeat two or times to get all of it. it is a pain to clean. it took me three tries. taking it out is last but most effective. my 98 626 did same thing it started as just astumble at takeoff then when ever you give it gas when driving. mostly on hills and if give more gas runs fine.

with no wiring guide on your Jeep, i visit grant you with a wager - The 'conventional' thanks to wire the TPS sensor is to take conventional automobile voltage & feed that into the sensor. The 12 vac then is going via the sensor, it extremely is only a variable resistor, & into the workstation. the workstation reads the voltage & estimates how some distance the throttle body is open. sounds like the TPS is going south on you.....
