I just wanted to see if everything worked out okay and your check engine light disappeared. And if there are any gotchas I should look out for.
No problem, that's the beauty of the internet.
Yes, code went off. I disconnected the battery while doing the exchange. Left the battery off for about 30 minutes; code went off after.
If you are replacing the same exact one as my problem - part number ending in 200 I believe, it's an easy switch compared to the other sensors.
Just make sure you have the same length of wire (if it's not the same length, you will know you got the wrong one). I suggest you change it from the top (the harness connector first) then drop the actual sensor to screw in the hole at the bottom of the car. Unless you have someone that can fish you sensor down to you.
Make sure to have a jack stand because you will be going under the car; I wouldn't risk it with just the jack.
I did have trouble trying to unhook the plug from the top - it's just a plastic clip, just make sure not to break anything.
Oh, also a Hyundai tech suggested that I do this: do this in the morning when the engine is cold. Start the car cold, rev till 2,000-3,000 for 20 secs or so then turn it off. That should make it easier to unscrew the sensor.
Let me know how it works out for you.
