Nissan Leaf Oxygen sensor

Description

Restore your Nissan’s optimal fuel economy and prevent costly catalytic converter damage with a new Upstream Oxygen Sensor (O2). This critical pre-cat sensor monitors the exhaust gas, enabling the Engine Control Unit (ECU) to maintain the perfect air-fuel ratio. A failing sensor causes poor performance, rough idling, and often triggers the “Check Engine Light.” Ensure your vehicle passes emissions tests across Australia.
