To replace the O2 sensor in a 2001 Toyota Tundra, first ensure the engine is cool and disconnect the negative battery terminal. Locate the O2 sensor, which is typically found on the exhaust pipe or manifold, and use a wrench or O2 sensor socket to unscrew it. Install the new sensor by threading it in gently, and then reconnect the electrical connector and battery terminal. Finally, start the engine to check for proper operation.
