The 5-wire wide-band oxygen sensor is a replacement sensor for select 2016-2025 Honda applications in the upstream position. It measures the exhaust air-fuel ratio across a broad range so the engine computer can meter fuel precisely. A built-in heater brings the element to operating temperature quickly after a cold start.
