How do you change the oxygen sensor on your 94 Toyota T100?

To change the oxygen sensor on a 1994 Toyota T100, first, locate the sensor, which is typically found on the exhaust manifold or downpipe. Disconnect the electrical connector and use a socket wrench to unscrew the old sensor. Before installing the new sensor, apply anti-seize compound to the threads, then screw it in and reconnect the electrical connector. Finally, start the engine to ensure it's functioning properly and check for any warning lights.
