This genuine Nissan oxygen sensor is located in the exhaust system, before the catalytic converter. Often referred to as the front or upper O2 sensor, its primary role is to measure the amount of unburned oxygen in the exhaust gas as it exits the engine. This information is sent to the Engine Control Unit (ECU) to precisely adjust the air-fuel mixture for optimal performance, fuel economy, and emission control. Over time, these sensors can become fouled or fail, leading to incorrect readings and negatively impacting your vehicle's 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.
Please make sure this is the correct sensor you are after, as returns will not be accepted for incorrect choice.
They cannot be interchanged, as they are programmed to work differently with the ECU.
