DENSO Auto Parts 234-9100 left air / fuel ratio sensor for the 2010-2013 Lexus LS460 V8 4.6L measures oxygen in the exhaust for the engine computer. This DENSO Auto Parts air fuel ratio sensor is a wide-band type made and tested to OE standards.
A worn or failing air / fuel ratio sensor can show up as a check engine light, rough running or poorer fuel economy. Before you replace it, look over the wiring and connector for cracks or melted insulation with the engine off and cool; damage there can give readings that look like a bad sensor.
