This genuine Nissan oxygen sensor is for the FRONT LOWER after the Catalytic Converter. It is a critical component of the engine management system, constantly measuring the amount of unburnt oxygen in the exhaust gases. This information is sent to the engine's computer (ECU) to make real-time adjustments to the air-fuel mixture for optimal performance and efficiency.
You may need to replace this sensor if it becomes contaminated or fails with age. Common symptoms of a faulty oxygen sensor include a lit 'Check Engine' light on your dashboard, a noticeable decrease in fuel economy, rough idling, or poor engine performance.
The earlier TB48 engines have 2 Oxygen sensors and the later models have 4.
2006 onwards models have 4 sensors, and the 2 upper ones were also changed after 2006. So please check the pictures of the plugs in the photo before purchasing. The earlier plugs are 4 pin wide. the later are 2 rows of 2 pins.
