Nissan Sentra Upstream Oxygen Sensor, Lambda Air Fuel Ratio
Keep your Nissan running clean and efficient with the Nissan Sentra Upstream Oxygen Sensor, a precise lambda sensor designed to monitor exhaust oxygen levels and help the engine control unit maintain the optimal air-fuel ratio. This upstream sensor uses magnetic induction with a heating element to deliver fast, accurate readings even during cold starts, ensuring smooth idling, improved throttle response, and reduced emissions. It’s a direct-fit replacement engineered to match OEM performance for reliable repair and long-term engine health.
The sensor is compatible with a wide range of Nissan models, including Cube, Versa, Sentra, Altima, and Maxima, across several years. Key compatibility includes Nissan Sentra 2.0L and 2.5L variants (2008–2012), Versa and Cube, and Altima/Maxima configurations where indicated as upstream sensors. OEM part numbers and their equivalents ensure a reliable cross-reference with your existing wiring harness and connector style, including 234-9039, 22693-1AA0B, 2349039, 226931AA0B, 22693ZJ60B, 22693-ZJ60B, 25679, SU11715, 211200-7060, and 2112007060.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
