How do you replace an oxygen sensor on Daewoo Leganza?

To replace the oxygen sensor on a Daewoo Leganza, first, ensure the engine is cool and disconnect the negative battery cable. Locate the oxygen sensor, which is typically found on the exhaust manifold or the exhaust pipe. Use a wrench or oxygen sensor socket to unscrew the old sensor, then apply anti-seize compound to the threads of the new sensor before installing it in the same position. Finally, reconnect the battery and start the engine to check for proper function.
