To replace the oxygen sensors on a 1999 Volvo S80, first, ensure the vehicle is cool and safely elevated. Locate the oxygen sensors, which are typically found on the exhaust manifold and downstream in the exhaust system. Disconnect the electrical connectors and use a specialized oxygen sensor socket to unscrew and remove the old sensors. Install the new sensors by threading them in, tightening them securely, and reconnecting the electrical connectors.
