This sensor is a non-heated type, which means it relies on exhaust heat to reach operating temperature rather than an internal heating element. The 20-gauge wiring and 17.44-inch harness length provide reliable electrical connectivity, while the radiused polygon male connector ensures a precise and secure connection to the vehicle’s wiring system. The flange mount design with an 18.0 mm thread diameter allows for straightforward installation and stable sensor positioning within the exhaust system. With an overall length of 20.98 inches, this sensor fits seamlessly in the designated mounting location on the Toyota Celica.\u003c\/p\u003e\u003ch2\u003eWalker Products OE Brand Line Information\u003c\/h2\u003e\u003cp\u003eWalker Products OE is a product line focused on delivering original equipment quality emission control components.
