  1. 1

    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.

  2. 2

    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.

  3. 3

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

  4. 4

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

  5. 5

    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."

Tips and warnings

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