It sends a signal to the engine control module to help optimize emissions control and regeneration cycles. A failing sensor can cause check-engine lights, poor regeneration, reduced power, or derate, so it’s replaced when diagnostic trouble codes point to EGT sensor faults or when the sensor becomes physically damaged or contaminated.
