BOSCH 15473 Premium OE Fitment Oxygen Sensor - Compatible with Select Acura EL; Honda Civic

This is an exact fit O2 sensor. I purchased if for me '04 Honda Civic EX, 1.7L Engine.This is the cheapest price I found (at $157), and oh believe me, I looked EVERYWHERE. (if you were to purchase this item from stores such as Advanced Auto Parts, you'd be paying around $269)Who would thought this little thing would cost so much?There is not much to say about the part, I mean it is the perfect/ exact fit, and is very easy to replace (with a little muscle to get the old O2 sensor off).I highly recommend this part, and do not delay in replacing it. my car started to stutter once I hit 80mph. It was scary for the car to loose acceleration when you are on the middle of a highway. So don't down play the importance of this little part. I guess it cost that much for a reason huh?

I used it for my 2005 civic Honda upstream o2 sensor so far it’s run ok need more mileage to see how well it will perform thx

First off, excellent buy from the "Used- very good condition" selection for 64 bucks. Identical to the original removed form a 2005 Honda Civic EX in wire length, plug wiring, thread length and depth, and bracket grommets.i just used a squirt of B'laster 16-PB Penetrating Catalyst, which is sold here on Amazon and let it sit on the cold sensor threading for some time. I used the short 1/2" drive O2 socket, OEMTOOLS 25249 Oxygen Sensor Crowfoot Wrench, which is also sold here on Amazon. I did use a long handled flex-head 1/2" drive ratchet, the longer handle really did help. I applied a steadily increasing pressure and all at once it "popped" loose, so be careful of what you're near and all. Unscrewed easily after the "pop", Mine had two grommets which were held in bending brackets which keeps it away from the hot piping and guides it to the plug. When I installed the new one I started with the sensor, put a very light brushing near the top of the threads using Permatex 80078 Anti-Seize Lubricant , just be careful to not overdo it and none on the actual sensor just the upper threads. Screwed in effortlessly. routed the covered wiring one at a time, my brackets were very old so i chose to also use a zip tie at each grommet point for extra insurance, making sure to guide it away from any parts and hot piping. I plugged it in and added a slight touch of dielectric grease on each backside of the plug to prevent moisture from entering, just a extra step. Pretty easy job really, just make sure to use a rust buster spray and let it sit, and to route the new cable carefully, you can do it!4/19/2021 Update : Still working great, no problems.

This is a great OEM replacement for the 04-05 civic 1.7l vtec motor. One of the best prices (at the time) on the net. Only $160.So I ordered it a few weeks ago. Received it. The box was right, it had the 15473 product number on it, but when I opened it up, inside was a GENERIC no name made in china sensor, not the beloved made in Japan Bosch sensor. Ok, maybe there was a mistake, so I used Amazon's easy exchange policy, sent the wrong one back and picked up my new one from the post office.Surely I thought, the same mistake can't happen again. Guess what, it did. THE EXACT same problem. The right product packaging with the wrong item. The o2 sensor inside wasn't even a wrong bosch sensor, it wasn't Bosch at all! A cheap generic Chinese ripoff of a sensor. The guy below me seemed to have ordered his at the same time, but he seemed to have gotten the right one. Perhaps the warehouse I was getting mine shipped from had screwed up royally, or perhaps the vender Amazon was getting these o2 sensors from had screwed up form the factory.Who knows, but to say I was disappointed to get the wrong product TWICE, is an understatement. I called Amazon and let them know of this gigantic screw up, and that they should check into this problem so other people don't get screwed like I did. I notice now, a few days later, the posting is back up, but now its selling for $211 instead of the $160ish it cost me at the time. I don't know what the heck Amazon is doing. So buyer beware, maybe they fixed the problem, maybe they did not. I would have loved to receive this Wideband bosch sensor, as its an EXCELLENT sensor, and in fact is an upgrade from the OEM in my opinion, but now I have to buy elsewhere. Rockauto has great pricing luckily.

Replacement air/fuel sensor ... for the 2005 Civic EX in our case. Our civic was throwing a P0134 error which is a problem with the first sensor ... the one before the catalytic converter. Unlike a typical "oxygen (O2) sensor" these things are *expensive*. Dealer was talking in the $400+ range for diagnosis, part, and install. Having to replace critical emission control equipment at 80,000 is a failure on Honda's part... I read this is a common problem for the Civics.This is not a difficult repair for the DIY. The sensor can be reached from under the car and you only need an open end wrench (7/8" works), not the typical O2 sensor tool sold for these gizmos. I was expecting the dead one to be stuck due to living in the exhaust stream for 80k miles but the anti-seize compound did it's job and it came out without a struggle. (note: the new sensors arrives with anti-seize on threads) The Haynes manual suggests that you run the car a couple of minutes to heat things up and that will help the removal. (The exhaust will be hot if u run the car, don't get burned.) I also sprayed the sensor - exhaust connection with penetrating oil before beginning.So unplug and remove the old sensor, thread in the new one and plug it back in to the wiring harness. I pulled the fuse for the PCM during the replacement ... once the new sensor was plugged in the check engine light was cleared and we've been good to go since.
