Genuine Hyundai 39250-2B000 Knock Sensor Assembly

Perfect fit accent 2012 1.6 mpi

My check engine light went off after installing. 💯

Works, without removing the intake manifold! No special tools if you're handy.

Fits 2013 Hyundai Veloster. No turbo. A tad aggravating to replace but I did it.

Excelente calidad amigo. Gracias

This part cleared the error. Don't hesitate. Buy it now. Update 1 year: I’m knocking off one star. 3 or 4 times the engine light has come on with a knock sensor error. I’ve ignored it and it has gone away after a couple days.

Would purchase again

First, when I ordered this item, I received an estimated arrival time of 2 days. I waited and instead it came in a week, while in the meantime my car ran very bad. I got the knock sensor, finally found someone to put the part on my car, and within 2 days the car was running worse than it did before the knock sensor was replaced. Within 2 weeks the check engine light came back on, and for 2 days I was able to drive more than 50 mph on the highway (how I get to work an hour away) without the car shuttering and knocking, not to mention the resistance of acceleration every time I pushed on the gas pedal. I should've known the price was too good to be true, but with all of the successful items I've gotten from Amazon, it didn't even register that I would get a bad part. Now I know, and never again. I'm extremely disappointed.

It came about a week late, that was the only downside. If you're replacing this yourself and watch youtube videos to see how and they say you need to remove the exhaust manifold, they are wrong. You can get it from under the car. Use the smallest ratchet in a set with a 12mm socket and you'll get it out. A very serious note though, the bolt is only tightened to 12 ft/lbs. So when reinstalling it, go hand tight, and then one quarter turn and that's all you need. Too tight and you could crush the internals of the sensor or cause it to be too sensitive. If your check engine light is still on after installation and doesn't clear after about 100km driven, disconnect your battery for about 15 minutes and it will clear it.

Much cheaper than the OEM by original manufacturer and also auto parts stores. Best to replace under the vehicle than take apart the top. Underneath you need to remove a "C" shaped cover and then gain access to the old knock sensor up and behind the oil filter for the engine. It is tight in there and I had to use a flat wrench rather than a ratchet wrench. Faster than anticipated deliver also. Thanks.

Works great. A little challenging to install but the light went out, and stayed out.

Had a check engine light on a 2014 Kia Rio , after checking the code with the code reader . I got code P0235 This code is the Knock sensor , I was impressed to find an OEM Part for Kia and Hyundai . Best thing of all it was cheaper than the dealer . Its somewhat of a hassle to replace but then again I'm a mechanic by trade ..Thank you Amazon !
