Works so far
Car started up and ran great. So far so good. We will see if it lasts. Can't been the price... Even if it was just to test if it fixed the problem.

14 Ford Expedition, NOT Plug and Play
For a 14 Ford Expedition, this is NOT "plug and play". This vehicle only uses 4 of the 6 wires, the outer wire on each side is not used. Also the color coding does not totally align; the yellow brown from the car goes to the purple black, the blue goes to the blue white, green to green orange, and purple gray to blue black. Other applications are probably different. Please be careful! (NO, I did not leave it like the picture, that is just to show the proper connections for my vehicle)

No. Do Not Buy!
Bought this sensor to replace the factory sensor and cure the MAF code that popped up. After installing, the code DID NOT resolve. Ended up going to AutoZone and paying twice as much for a part that works. Code resolved. Buyer beware: cheaper IS NOT better. Just buy a reputable part from a reputable vendor and save yourself the trouble. Pretty sure these are cleaned up sensors sold as new replacements. AGAIN, DO NOT BUY!
