Lambda Sensor (Oxygen Sensor)
This Lambda Sensor (Oxygen Sensor) is an Original Equipment (OE) component manufactured for the General Motors (GM) group and its affiliated brands. The OE numbers 96377500 and 25165116 are directly interchangeable and refer to the same physical sensor, widely used across Chevrolet, Daewoo, Opel, Vauxhall, Buick, Cadillac, GMC, and other GM-family vehicles.
The sensor monitors oxygen content in the exhaust gases and relays this information back to the Engine Control Unit (ECU) to ensure the optimal air-fuel mixture is maintained throughout operation for efficient combustion.
