To replace the O2 sensor on a 2003 Kia Optima, first, ensure the engine is cool and disconnect the negative battery terminal. Locate the O2 sensor, typically found on the exhaust manifold or after the catalytic converter, and use a wrench or O2 sensor socket to unscrew it. Install the new sensor by threading it in and tightening it securely, then reconnect the electrical connector and the negative battery terminal. Finally, start the engine to check for any warning lights or exhaust leaks.
