O2 sensor replacement

Hello Jessica, you will be happy to know that this isn't going to be difficult for you to replace at all. If you can get under your car safer and know how to turn a wrench then your going to be just fine. The attachment shows you exactly what you are going to see lying on your back underneath your car. Safety is your best friend and you will need to use your best friend in lifting one side of your car with a jack and placing a solid object like a big block of wood or a jack stand and lower the car onto it. Now with the car in the air slide underneath and find the o2 sensor circled in the attached photo. Take a wrench the same size as the sensor and loosen the sensor a bit and unplug it. Then finish unscrewing it all the way out. Installing the new one might require a special wrench available at any auto parts store to rent for free!! Hope this helps !

Okay, how do I know which one to buy at the parts store? Because they need me to find out which one they said.

Thank you.

My question is, what is the part number or how will I know if I go to O'Reillys.com for example how do I know which one to get?

Hello, I'm Danny.

I've attached a picture below of the factory Hyundai Bank 1 Sensor 2 part number. When you go to any of your local auto parts stores just use this number to have them cross reference their aftermarket store brand sensor for you. Hope this helps and thanks for using 2CarPros.
