Hello family-- The oxygen (O2) sensor monitors the air-fuel mixture of your engine by measuring the amount of oxygen in the exhaust gas. Your car will run best with the right air-fuel mixture and the O2 sensor sends a message to your fuel injectors whenever it detects the wrong mixture. I will send you to a diagram of the location of those sensors on your 1991 Toyota Previa. Just click on the diagram for a full-sized view.
