The 4-wire narrow-band oxygen sensor is a replacement sensor for select 1994-2020 Chrysler, Dodge and Mitsubishi applications. It signals whether the exhaust is running rich or lean so the engine computer can trim fuel delivery. A built-in heater brings the element to operating temperature quickly after a cold start.
