Lambda Sensor (Oxygen Sensor)
These Lambda Sensors are Original Equipment (OE) components manufactured for the General Motors (GM) group and its affiliated brands, as well as Mazda vehicles. The OE numbers 96253546 and 96567235 are both used across Chevrolet, Daewoo, Opel, Vauxhall, and other GM-family vehicles.
These sensors monitor oxygen content in the exhaust gases and relay this information back to the Engine Control Unit (ECU) to ensure the optimal air-fuel mixture is maintained throughout operation for efficient combustion.
Important Note: These are two different sensors with different specifications and applications. 96253546 is typically a 2-pin, unheated sensor used in the upstream (pre-catalyst) position, while 96567235 is a 4-pin, heated sensor also used in the upstream (upper/first) position. Always verify your original sensor's specifications before ordering.
