Throttle position sensor

[shadon98]

I never thought it would be this difficult to find the right part when I have the original part number. Check engine light came on my 99 wrangler 2.5l and coded a P0121 throttle position sensor. Part number on my sensor is 56027942AC. I can't find any cross reference. A part number 04874371AC came up and said it was compatible, but another Mopar parts site checked my vin and couldn't find a match and said that number doesn't fit my Jeep. It shouldn't be this freak'in difficult. Has anyone come across a problem kike this?

I show part number: 4874371

I'd go with a NGK unit

That was the number I was told wasn't a fit for a 99. Also, that one doesn't have the O-ring gasket. Apparently some years don't require the O-ring gasket. Seems like an air leak waiting to happen.
Someone got back to me and said the Dorman 977-519 was a match. There are several different makes and part numbers, unfortunately none are direct match to the OEM number. It's kind of a crapshoot at this point.

This one shows your OEM part number as an interchange. Ill always trust a NGK brand like Doug suggested , but Ive also used these standard motor products electrical parts with good success.

Rockauto has it listed for a 99 2.5 L. IDK

You can drop it off at Kohls if you don’t want to ship it yourself.

Fun fact, you can drop off a gallon ziplock bag with a shattered sealed beam from an XJ that burned out prematurely then shattered into a million pieces because it was freezing cold out and you fumble fingered it.
