How do I Change the O2 Sensor on a 2002 Hyundai Santa Fe

The 2002 Hyundai Santa Fe is equipped with two oxygen (O2) sensors within the exhaust system. Designed to control the fuel consumption based on the oxygen in your cars exhaust, the oxygen sensors thread into the exhaust manifold and catalytic converter of your Santa Fe. When the cars fuel economy begins to decrease significantly, you may need to replace the oxygen sensors. Buy replacement sensors from an auto parts retailer and change them at home in minutes.

Instructions

1

Raise the Santa Fe with a jack and support it on a set of jack stands. Locate the oxygen (O2) sensors along the exhaust system.

2

Pull the electrical connection from the top of the oxygen sensor. Remove the existing sensor with an oxygen sensor socket and ratchet.

3

Thread the new oxygen sensor into place by hand to avoid the risk of cross threading and damaging the sensor. Torque the sensor to 40 pound-feet with your torque wrench. Push the electrical connector back into place until it clicks.

4

Repeat the process on the second sensor, if needed. Raise the car slightly with the jack to remove the jack stands. Lower the car to the ground.
