To determine if you have a bad oxygen sensor on a 1992 Lexus LS400, you can look for symptoms such as poor fuel efficiency, rough idling, or a check engine light. Additionally, you can use an OBD-I scanner to check for trouble codes related to the oxygen sensor. If the sensor is malfunctioning, it may also show fluctuating voltage readings when monitored in real-time. It's advisable to replace the sensor if it fails these tests.
