Model Number:
LR011711
Product Overview
The LR011711 rear oxygen sensor (lambda sensor / heated exhaust gas oxygen sensor) is a direct OEM-equivalent replacement for the for Land Rover Range Rover L322 (2010–2012) fitted with the 5.0L V8 petrol engine – both naturally aspirated and supercharged variants. This sensor monitors oxygen levels in the exhaust stream after the catalytic converter, providing critical feedback to the Engine Control Unit (ECU) for precise air-fuel ratio adjustment. A failing rear O₂ sensor triggers the check engine light, reduces fuel economy, or causes failed emissions tests – replace it to restore engine efficiency and emissions compliance.
