Code P1196 Chevrolet Description

The P1196 Chevrolet diagnostic trouble code (DTC) specifically refers to an issue with the Exhaust Gas Temperature (EGT) Sensor 3 performance while the engine is running. The EGT sensor is a crucial component in modern vehicles that monitors the exhaust gas temperature to ensure optimal performance, fuel efficiency, and emissions control. This sensor is typically located in the exhaust system and sends data to the engine control module (ECM) to make necessary adjustments.
