The 4-wire narrow-band oxygen sensor is a replacement sensor for 2007-2008 Renault Euro Clio, 2010-2011 Renault Sandero and 2010-2017 Renault Stepway with the 1.6L I4 engine. 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.
