To replace the oxygen sensor on a 2002 Toyota Sequoia, first ensure the vehicle is turned off and cool. Locate the faulty oxygen sensor, typically found in the exhaust system; it may be mounted on the exhaust manifold or downstream in the exhaust pipe. Disconnect the sensor’s electrical connector and use a wrench or oxygen sensor socket to unscrew and remove the old sensor. Install the new sensor by threading it in place, reconnecting the electrical connector, and ensuring it's secure.
