Good for the price, it fits my Ford Escape as expected. Easy install, the dificult parte is reaching out the right spot. Currently working fine. I can feel my car running a bit faster. At least for now it is working great.

It appear to be a good quality part.

Check engine light on 2011 Fiesta SEL came on. Ran the diagnostic tool and got error in the picture. If you do not have a scanner to pull codes a local store like Advanced Auto or similar will do it for free.
This Walker Brand sensor was the cheapest by far and with all positive reviews I went for it. Also note that the Fiesta can use this same sensor for either of the 2 sensors on this vehicle, they are the same.
As far as replacing it, in theory its as simple as popping the hood unscrewing the old one disconnecting the cable and replacing with the new one. If you can make toast from a slice of bread you should be able to do this.
There is also a “special” oxygen sensor removal tool you can borrow for free at places like Advanced Auto to help remove the bad one.
Just be sure you are taking out the right one, the second one you can see more easily from the viewing point/angle from above. Its deeper and lower in the engine compartment.
Well what really happened. I could barely see this sensor where it screwed into its place. You can definitely access it from the top and run your hand to it to get a feel of where it is. But the space is extremely tight. I tried like hell with the “special” tool that was supposed to help along with a good about of B’laster spray but that thing would not budge. Long story short a good heavy duty wrench that is either 7/8 or 22cm got it loose with some muscle a lot quicker. Again you are doing this all on feel as you do not have a good angle to see it very well.
Once it was out added a little anti seize grease on the new one, felt where it goes, screwed it in and connected the cable.
In my case my check engine did not go off right away. I ran out and did some errands and by the next day the check engine light was off and has been that way so far for a few days. I could have reset the code with the diagnostic tool but preferred to let things work themselves out and reset on its own.
For what its worth the car has a 162,000 miles on it. With all the transmission issues/recalls who knew it would still be running and getting about 38mpg!!

I ordered this part to resolve the following error code:
P0053 Code: Heated O2 Sensor (H02S) Heater Resistance (Bank 1, Sensor 1)
I replaced the old sensor with the one I ordered and I still have the same problem. I am pulling my hair out at this point.

Two things to know before reading this review:
1) I am an incurable miser…in extremis!
2) This sensor HAD to work as I had to smog check my car to renew its registration…just before leaving for a 3-month trip!
I have a 1999 Ford Contour SE Sport 2.5L V6 and “mistakently” ordered this part (should be 250-24302!) because another website said it was meant for a failing pre-cat. Turned out to be the cheapest O2 sensor (w/FREE SHIPPING) on Amazon, something near to every Pinch-Penny’s heart! When I discovered the discrepancy by consulting Walker’s website, I promptly searched for more info. This sensor apparently is meant for the Ford Econoline E-series vans. I also found that so-called “universal” sensors would substitute equally well for my car and the vans. I presumed, therefore, that the only difference would be the connector. I fretted about this until it arrived and found alternate sources for the correct part should my assumption prove fatal. As you can probably tell by the 5-stars everything worked out great! Removing the part from my car it looked identical to this one (same threads, same configuration, same wire length, etc) EXCEPT for the connector. Furthermore, the connector was easily disassembled and swapped so that in 5 minutes, I had it ready for installation. It even came with anti-seize compound! Because of Ford design the part was difficult to access but well worth the effort: the car runs better now and passed smog with amazing numbers!
I wouldn’t recommend my substitution but I’m convinced this part would work adequately for its correct usage, too. I also ordered the CORRECT post-cat (Walker 250-24001), which worked well.

Got the P0054 code on my 2012 Fiesta SE.. A lot of good reviews, so I ordered the Walker sensor and a a split socket. 15 minute job. No more code.
