Description
The Toyota Mirai uses a highly sensitive Air/Fuel Ratio (A/F) sensor, a specialized form of oxygen sensor, to precisely monitor the exhaust from the fuel cell stack for emissions control and performance. Located in the exhaust system, this component is critical for the vehicle’s sophisticated fuel delivery and overall efficiency. Failure of this sensor can trigger the Check Engine Light, leading to poor performance and requiring replacement with a genuine OEM part to ensure proper function of your FCEV system.
