Each sensor is built to the vehicle-specific electrical and thread specifications listed below, so you can replace failing sensors without modifying wiring or mounts. The set is ideal when you need multiple sensors replaced at once for diagnostic repairs or preventative maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eWhich Lexus and Toyota models does this sensor set fit?\u003c\/h3\u003e\n\u003cp\u003eThe DriveFix set covers many Lexus ES, GX, LX and Toyota 4Runner, Avalon, Camry, FJ Cruiser, Land Cruiser, Sequoia, Solara, Tacoma, Tundra and Venza applications across specific model years and engine sizes.
