Oxygen Sensor Compatibility
Car Oxygen Sensor 1821384Z10/1821384Z50/96418965 For Chevrolet / Suzuki / GMC / Opel / Vauxhall
Product Overview
These Lambda Sensors are Original Equipment (OE) components manufactured for Suzuki, Chevrolet, Daewoo, Pontiac, GMC, Opel, and Vauxhall vehicle groups. The OE numbers 1821384Z10, 1821384Z50, and 96418965 are closely related and frequently listed together as interchangeable references across multiple aftermarket catalogues.
These sensors monitor oxygen content in exhaust gases and relay information to the Engine Control Unit (ECU) to ensure optimal air-fuel mixture for efficient combustion and reduced emissions. They feature a 4-wire heated design with rectangular connector, allowing quick operating temperature achievement for precise air-fuel ratio measurement.
Important Note: These three OE numbers represent different sensors with varying cable lengths and connector configurations, though they are closely related and often grouped together in parts catalogues. Always verify your original sensor's part number, connector shape, cable length, and position before ordering.
