Code P1196 2017 GMC Sierra Description

The P1196 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a problem with the Exhaust Gas Temperature (EGT) Sensor 3 performance while the engine is running. The EGT sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. This information is crucial for the engine control module (ECM) to adjust fuel delivery and optimize combustion efficiency. When the EGT sensor 3 is not performing as expected, it can lead to various issues affecting the vehicle's performance and emissions.
