Maintain accurate exhaust monitoring and catalytic converter efficiency with this Genuine Nissan Rear Oxygen Lambda Sensor, designed to suit Nissan Patrol Y62 Series 1-2 models fitted with the VK56 5.6L V8 petrol engine. This OEM rear oxygen sensor is fitted in the exhaust system before the second catalytic converter, where it measures oxygen levels in the exhaust gases and provides important feedback to the Engine Control Unit (ECU) to monitor catalytic converter performance.

Over time, oxygen sensors can become contaminated, slow to respond or fail due to constant exposure to extreme exhaust temperatures, fuel additives and combustion by-products. A faulty rear oxygen sensor can cause incorrect exhaust readings, trigger engine fault codes, reduce fuel efficiency and affect emissions performance. Replacing it with a Genuine Nissan component restores accurate exhaust monitoring and helps maintain correct engine management operation.
