Mopar 4874371AC Throttle Position Sensor by

Tried a cheaper one 1st it did ok but after a few months my jeep was jerking on acceleration. Read on forums that only Mopar will work. We'll it does work better than it ever did with the cheaper one.

My package never arrived. However, I ordered the same Mopar TPS elsewhere and if you get a genuine Mopar TPS it will save you trouble and hassle down the road because the generic ones either don't last or don't work properly from the get go. Mine was for a 2001 Jeep Wrangler. I thought I had something else going on after the 2 generic sensors didn't solve my problem, but then like magic the Mopar one did!

I was concerned this was not going to be an OEM part after reading others reviews. I had bought a non OEM part from a local auto parts house and it did not work, in fact the jeep ran worse after installing their part. After receiving the part from Amazon it came in OEM packaging, installed the part and my jeep hasn't ran this good in years. Part from Amazon was a an upgraded part but fit perfectly.

Bought this thinking it was OEM, the picture displayed is nothing like what was sent, no oring and the screws are silver and not the darker color. It doesn't even have the part number on the sensor. Compared to an actual OEM.

Purchased this for my 1998 Jeep Cherokee (XJ) 2dr 4x4 4.0l I6Local dealer wanted around $100, and I'd have to wait. Would've considered paying the large premium to walk out the door with it, but having to wait either way, I'd rather go here and pay way less.Original OEM Mopar sensor(~150k mi) would give occasional erratic throttle and/or hesitation. Replaced that some time ago with a Standard Motor Products TPS from rockauto. That thing never seemed to index right, and died during a reinstall swapping throttle bodies. Decided, foolishly, to cheap out since I was poor from holiday shopping and got a $9 one off fleabay. Figured, "hey, it's a simple freaking potentiometer, what could possibly go wrong?" W/in the month it was causing constant irregular and erratic throttle. Seller wouldn't exchange, only return, at my cost for shipping. Saw that scam pretty quick there and just decided to spend the money on a true Mopar part. So far, even though it's painful to think I spent so much on a simple freaking potentiometer, it's been working better than anything previous; and, hey, if the original lasted for 150+K miles, I'm betting this one will outlive a good deal of the rest of my heep.

Purchased Jan 2021. I can say with confidence that the sensor I received was in fact a Mopar unit. No fitment or quality issues. Tested with an analog multi-meter prior to final installation and this sensor maintained a clean sweep through its range.

Tried the cheaper aftermarket, but still had engine light- This OEM part fixed it. The aftermarket part is only $30 and it is hard to bring yourself to purchase this $80 part, but in the end.....I shelled out more money because the aftermarket did not have the quality airtight fit needed.ADDITIONAL INFO 11-14-13If you need TPS, this is the one! In the end I had more engine light issues with codes pointing to up front bank O2 sensor, I changed those... still issues. FINALLY I found a thread that discussed issues with Ethanol causing problems with air/fuel mix. So now, not certain if it was ever my TPS, O2 sensor or muffler. I only know since doing all that and SeaFoam in my intake....after NOT use Ethanol fuel, 8 months later NO ENGINE LIGHT! My suggestion- Check Gas cap first ($8), avoid Ethanol fuel (Jeep Forums discuss this with 4.0), then try TPS, O2 ups (CA Jeep you have 4 O2 sensors, lower will not mess with air/fuel to set off light) Also.....when you change any of these things, a reset by disconnecting your battery overnight, never hurts. Let your computer adjust to the changes you have made or you may end up with a false/positive engine light.

My Cherokee has 246,000 miles and I’m gonna keep driving it so I figured it was time to update all of the sensors with high quality parts.The Jeeps performance is actually better now!
