    GM part number 12683525 is an OEM Exhaust Gas Temperature (EGT) Sensor (also called an exhaust temperature sensor). It reports exhaust gas temperature to the engine control module, which uses the signal to help manage fuel delivery, turbo boost, and protect emissions components such as the diesel particulate filter (DPF) from overheating.

    Common fitment includes diesel-powered:

    • Chevrolet Silverado 2500 HD (2017–2024, 6.6L Duramax)
    • Chevrolet Silverado 3500 HD (2017–2023, 6.6L Duramax)
