Older Model Vios Rear Oxygen Sensor 89465-0D180 Stable and Durable, Easy Replacement

When your Yaris shows check engine light, noticeably increased fuel consumption, or rough idle, the rear oxygen sensor aging or failure is likely. This sensor monitors exhaust oxygen content and feeds back to the ECU to precisely control the air-fuel ratio, ensuring emissions and power are smooth. OEM number 89465-0D180, fits older Yaris models. During installation, perform in a cold state, and avoid contact between sensor wiring and high-temperature exhaust sections to prevent damage.
