GM / Delphi 2-Pin Female Waterproof Sensor Connector – OEM 12162852
Direct OEM-specification replacement for the Delphi 2-pin female waterproof wire harness connector used on sensor circuits across General Motors platforms. Cross-references Delphi / GM OEM part number 12162852. Black nylon housing with waterproof sealing — a widely used 2-pin sensor connector across GM’s engine management, body, and chassis harness applications on Chevrolet, Buick, Cadillac, GMC, and Opel platforms.
The 2-pin Delphi sensor connector is used across a wide range of sensor circuits on GM vehicles. A failed connector causes the ECM to lose sensor data, triggering fault codes and causing the engine or body system to operate in a degraded mode. The waterproof housing provides sealing for underbonnet and underbody sensor applications where moisture exposure is constant.
