Yikesai 4X Backup & Reverse Sensor Kit, Rear Parking Assist Sensor Compatible with Ford F150 F250 F350 E150 E250 Escape Explorer, Lincoln Mercury Mariner, Replaces 684-029 3F2Z-15K859-BA

These sensors were cheaper than the same parts at a junk yard (and the junk yard parts were all no good). These do NOT exactly match the appearance of OEM when installed, so even if you have only one that needs replacement, you'll want to replace all 4 if you care about them matching in appearance. They are not hard to replace and fit perfectly with the OEM housing for my 2006 F-250. They fixed my park assist system and work great now.

It fixed my problem! So much cheaper than OEM and works the exact same!

Fixed the faulty backup sensors on my used 2011 super duty. Installed pretty easily. I only replaced the bad ones and kept the extras for spares. It's actually easy to tell which ones are bad. You shift into reverse to activate them and if you go the back of the truck you actually here them repeatedly clicking if they're working. Replace the silent ones and you're back in business. Easy peasy.

Gave 4 out of 5 stars because 1 sensor didn't work as well as the others. I installed all 4 sensors in my 2006 Ford Explorer to replace 1 defective one. I did this so they would all match. However when I tested them, 3 of them would beep and then beep constantly when I was moving my hand by the sensor, 1 of them only beeped a few times and never increased the frequency the closer I put my hand to it. I replaced that with 1 of my old ones and it worked fine. So overall these work, but make sure you check them before putting the bumper back together!

The part was just a little different color, but it fit like the original and it worked perfectly. I’ve had it installed for about a year now.

TRASH! Failed after a few days. Spend the extra money on some that are better quality and actually fit properly unlike these!

Arrived and was exactly as described

Decent quality, plug and play, easy to swap. But I believe one of the new ones I got doesn’t work sadly. Can’t hear the ticking noise like the others.

All worth it as they fit really well and work as they should.

I have a 2009 Ford Escape V6 3.0 Limited Edition and these sensors fit. As you can see from the picture they look different than the OEM part but they do fit. I believe it’s the same sensor for 2008 and 2009. The dealer part # is 4F2Z15K859A

works great

Capteur fonctionne correctement mais pas aussi bien que ceux d’origine mais cela fait la job.il faut rester prudent si on recule trop vite .Manque un peu de sensibilité.Il y en a un qui a été difficile à installer mais finalement tout est ok.reste à voir la durée de vie. Je recommande pour le petit prix

Works as it should.
