ACDelco 55499759 Exhaust Gas Temperature Sensor EGT

The ACDelco 55499759 is a GM Original Equipment Exhaust Gas Temperature (EGT) Sensor designed to measure exhaust gas temperature at critical points in your vehicle's exhaust system. This sensor reports real-time exhaust gas temperature data to the engine control module, enabling precise fuel delivery and boost pressure adjustments to protect exhaust after-treatment components from overheating.

Key Features:

• GM Original Equipment part - true OE component installed during production or validated by General Motors
• Monitors exhaust gas temperature before the diesel particulate filter
• Provides critical temperature data to the engine control module for optimal performance
• Helps protect exhaust after-treatment components from overheating
• Ensures efficient operation of emission control systems
• Designed and manufactured to meet rigorous GM specifications for fit, form, and function

This exhaust gas temperature sensor is engineered specifically for diesel-equipped GM vehicles, providing the same performance, durability, and service life you expect from General Motors Original Equipment. Proper exhaust temperature monitoring is essential for maintaining emission system efficiency and protecting costly after-treatment components.
