How to Replace an Oxygen Sensor in a Hyundai Tiburon

by Alibaster Smith

The oxygen sensors in your Hyundai Tiburon are located near the catalytic converter. There is one sensor in front of the converter and one behind it. The oxygen sensors, also called "O2 sensors," monitor the exhaust gases coming out of the engine. The sensors then send information to the Tiburon's electronic control unit (ECU) which adjusts the air to fuel ratio to optimize fuel consumption and horsepower. These sensors typically last for about 100,000 miles. When they finally fail, you'll need to buy a replacement sensor which can be found at most auto parts stores.

Step 1

Use the floor jack to lift up on the front jack point located just behind the radiator on the Tiburon. The jack point is an extension of the frame of the vehicle and is the only safe jack point on the front of the vehicle.

Step 2

Place a jack stand under each of the front pinch welds on the driver and passenger sides of the Tiburon.

Step 3

Lower the Tiburon onto the jack stands.

Step 4

Climb under the Tiburon and unplug the electrical leads from the O2 sensors. There are two sensors on the Tiburon, one in front of (before) the catalytic converter and one behind (after) the converter.

Step 5

Place the O2 sensor tool over the O2 sensor and turn it counterclockwise with a socket wrench to loosen and remove it.

Step 6

Thread and tighten the new O2 sensors using the O2 sensor tool and a socket wrench.

Step 7

Reconnect the electrical leads to the O2 sensors.
