Walker Products 350-34256 right oxygen sensor for the 2002-2010 Lexus SC430 V8 4.3L and other vehicles reads the oxygen in the exhaust gas to gauge combustion efficiency. The Walker Products oxygen sensor is a direct-fit unit that monitors the air-fuel ratio.
A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, but other faults cause the same signs. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage before you replace anything.
This oxygen sensor is a direct-fit replacement for a wide range of Lexus and Toyota models, including the 2001-2007 Lexus GS430 V8 4.3L and the 2001-2006 Lexus LS430 V8 4.3L.
