Maintain optimal fuel mixture control and emissions performance with this Genuine Nissan Oxygen Sensor, designed specifically for Nissan Patrol GU Y61 models fitted with the TB48 4.8L petrol engine. This OEM front lower oxygen sensor is installed in the exhaust system after the catalytic converter and plays a critical role in monitoring exhaust gases and relaying accurate data to the ECU for precise fuel delivery adjustments.

Over time, oxygen sensors can become contaminated or fail due to extreme exhaust heat, carbon buildup, and long-term exposure to combustion by-products. A failing sensor may cause poor fuel economy, rough idle, hesitation, increased emissions, or check engine light warnings, and can significantly impact overall engine performance.

Manufactured to genuine Nissan specifications, this direct-fit replacement restores accurate exhaust gas readings and ensures your engine runs efficiently and reliably under all driving conditions.
