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 — one of the most widely used 2-pin sensor connectors across GM’s global vehicle portfolio, fitted to temperature sensors, pressure sensors, position sensors, and speed sensors on Chevrolet, Buick, Cadillac, GMC, and Opel platforms.
The Delphi 12162852 connector is used on critical engine management and chassis sensor circuits. A corroded or open connector causes the ECM to lose sensor data, triggering fault codes and forcing the engine into a degraded (limp-home) operating mode. Because this connector is used across so many sensor types, a single failed connector can produce fault codes that appear unrelated — making connector inspection an essential first step before replacing any sensor.
