How to Replace an Oxygen Sensor for a 2001 KIA Sportage

Updated July 20, 2017

While an oxygen sensor for a 2001 KIA Sportage keeps the engine running at greatest efficiently, a clogged oxygen sensor can cause decreased fuel economy and environmental pollutants. A sign it may be time to replace the oxygen sensor in your KIA Sportage is low fuel economy, rough ideal or excess fuel exhaust. Follow these simple steps to replace the oxygen sensor in your Kia Sportage.

Locate the two oxygen sensors on the KIA. The 2001 KIA Sportage has two oxygen sensors, one on either side of the catalytic converter. The Sportage's oxygen sensors look like gold spark plugs coming off the exhaust manifold with an electrical wire on the end.

Remove the wiring harness from the KIA's two oxygen sensors. With your fingers, lift off the wire at the top of the oxygen sensor. Do not damage the end of the KIA's wiring harness.

Remove the Sportage's two oxygen sensors using the oxygen sensor socket wrench.

Apply the anti-seize lubricant to the Sportage's two new oxygen sensors and the connecting threads.

Install the new oxygen sensors in the KIA using the oxygen sensor socket wrench. Re-attach the wiring harness to both the KIA's oxygen sensors by pressing firmly until you hear a "click."

Tip

Let the KIA's engine run a few minutes before removing the oxygen sensors. The oxygen sensors can become stuck. A warm exhaust manifold can help loosen the oxygen sensors.

Warning

Use caution around hot exhaust systems. It only take a few minutes for the KIA's exhaust to get dangerously hot.

Things You'll Need

  • Oxygen sensor socket wrench
  • Anti-seize lubricant
