Specifications
Toyota Sienna (2011-2020) and Lexus ES/RX family engines of same displacement have rear oxygen sensor installed behind the catalytic converter (OEM 89465-0E040) to monitor exhaust oxygen in real time. It feeds back to the ECU to precisely adjust the air-fuel ratio, ensuring combustion efficiency and emissions compliance. This sensor is rear-oxygen-specific; installation difficulty medium; labor about 0.5-1 hour; avoid damaging threads during removal. If the vehicle shows check engine light, elevated fuel consumption, or weak acceleration, inspect this sensor.
