Land Rover Range Rover CPLA-9G444-HA oxygen sensor 0258030023 direct replacement.

Your Land Rover Range Rover may show engine fault light, abnormal fuel consumption, or unstable idle. This usually indicates aging or failed oxygen sensors unable to accurately monitor exhaust oxygen content. This sensor, when functioning properly, reports the air–fuel ratio to the ECU to ensure complete combustion and emission control. OEM number CPLA-9G444 (compatible with LR035748); fits Range Rover (2013-2021) and other models; can be replaced directly as an original part. When installing, ensure sensor threads are clean and tighten to the specified torque to avoid damaging the harness or gasket.
