As part of the emission control system, the o2 sensor for Toyota Sienna reads the air-fuel ratio of the exhaust fumes coming from the engine. The sensor concludes whether the mixture is too rich, meaning high oxygen content, or too lean, meaning low oxygen content. Either way, the sensor produces a voltage to the engine management computer, and in turn, the computer adjusts the fuel entering the engine. Purchase a replacement oxygen sensor for your minivan at any AutoZone store or online for Same Day Store Pickup (in most cases).
