Lambda Oxygen Sensor for Toyota & Lexus Vehicles
Original Equipment (OE) Lambda Sensors with part numbers 89465-05080, 89465-12750, and 89465-50180 are direct-fit components manufactured for Toyota and Lexus vehicles.
Product Overview
These genuine OEM Lambda Sensors monitor oxygen content in exhaust gases and transmit data to the Engine Control Unit (ECU) to maintain optimal air-fuel mixture for efficient combustion and reduced emissions. The 4-wire heated design ensures rapid operating temperature achievement for precise air-fuel ratio measurement.
As direct-fit components, they feature vehicle-specific electrical connectors and pre-terminated wiring for straightforward installation without cutting or splicing. Threads are factory pre-greased with anti-seize compound for easy replacement.

Cross-Reference Notes: These three OE numbers are listed together across multiple aftermarket catalogs as interchangeable references. 89465-12750 is specifically identified as the front (upstream) oxygen sensor for Toyota Corolla applications. Always physically compare your old sensor's connector shape (angular, 4-pin), cable length (435 – 492 mm), and thread size (M18 * 1.5) before purchasing.
Vehicle Compatibility
Important Position Note: These are upstream (pre-catalyst / front) oxygen sensors — installed before the catalytic converter. Do not use them in the downstream (post-catalyst / rear) position unless your vehicle's original sensor was located there. Upstream and downstream sensors are not interchangeable on most vehicles.
