Bad TPS, do I need a Mopar replacement?

My 2005 TJ has started having a high idle. I'll start it up, and the idle will be normal for two seconds, then shoot up to about 1900. Once warmed up it will idle at 1200 RPM. My code scanner said that I've got a bad TPS.


My question is, do I need a new Mopar unit, like this one:

Amazon.com: Mopar 5019411AD Throttle Position Sensor : Automotive

Or is it safe to cheap out and get one like this:

Amazon.com: ZBN TH266 4874371AD 5019411AD TPS Throttle Position Sensor Fit for Dodge Ram 1500 Jeep Grand Cherokee Liberty Wrangler 2002 2003 2004 2005 2006,5019411AA 5019411AB 5019411AC 229907 5086203AA TH415 : Automotive

From what I understand, a bad TPS could leave you stranded, but at the same time, I don't want to waste money I don't have to. The old balancing act..

Inhave bought amazon and ebay, plus rockauto and had no trouble. I never buy oem except on the trans cable for the rhd.

We just put a rockauto fuel pump in the 97 we just got amd it runs
 
My experience is non OEM brand fail right out of the box.

Consider cleaning it well. There is a post out there cleaning an TB IAC for dummies.

Check your TPS connection.

I had a 1990 XJ for 13 yrs. I replaced the TPS twice with an after market one during the first 6-7 yrs before replacing with a factory one so there maybe some truth in what JPN said. That TPS was still working correctly when I sold it.
 
Ordered a new Mopar TPS from Amazon. It was easy enough to swap in, and the engine sounds good. Now. Idles are where I'd expect.

I probably need to put more miles on it before claiming success, but things are looking pretty good.

The old one, as well as the wiring didn't look very bad. Is there a way to clean these?

Dirt gets inside. Actuating it 1/3-1/2 turns and compressed air.
