The sensor itself is located in the exhaust manifold between the engine and the fire wall.
Where are the oxygen sensors on a Nissan?
Your Nissan will have at least two oxygen sensors. One O2 sensor is upstream ( Bank 1- Sensor1 ) of the catalytic converter and can be accessed from the top of the engine. One or two sensors will be downstream, B1S2 and B2S2. The procedure is similar for the downstream O2 sensors (Bank 1 & 2, Sensor 2).
