Item description
General Motors Genuine Oxygen Sensor (Upper) 12659516
The General Motors Genuine Oxygen Sensor Upper (12659516) is a high-precision OEM emission control component designed to monitor oxygen levels in the exhaust gases of select GM vehicles. Engineered to meet strict manufacturer standards, this sensor ensures optimal air-fuel mixture, improved fuel efficiency, and reduced emissions.
The upstream (upper) oxygen sensor plays a critical role in engine management by sending real-time data to the engine control unit (ECU). This allows the system to adjust fuel injection for efficient combustion. Using a genuine GM part guarantees accurate readings, proper fitment, and long-lasting performance.
