How do you replace the 02 sensor on a 1992 mr2 toyota with a 2.2?

To replace the O2 sensor on a 1992 Toyota MR2 with a 2.2L engine, first, locate the O2 sensor, which is typically found on the exhaust manifold or just downstream on the exhaust pipe. Disconnect the electrical connector and use a wrench or O2 sensor socket to unscrew the old sensor. Install the new O2 sensor by threading it in and tightening it securely, then reconnect the electrical connector. Finally, start the engine to ensure proper operation and check for any exhaust leaks.
