ACDelco 55513243 Diesel Exhaust Particulate Sensor

The ACDelco 55513243 is a GM Original Equipment Diesel Exhaust Particulate Sensor designed to monitor the function of the Diesel Particulate Filter (DPF) in diesel-equipped vehicles. This sensor provides critical feedback to the engine control module by measuring soot concentration in the exhaust system, enabling precise control of DPF regeneration cycles.

Key Features:

• GM Original Equipment part engineered to exact factory specifications
• Monitors particulate matter levels in the exhaust stream
• Helps optimize DPF regeneration timing for improved fuel efficiency
• Reduces unnecessary regeneration cycles that can shorten component life
• Direct replacement for your vehicle's original sensor
• Manufactured to meet GM's rigorous quality and durability standards

This sensor is essential for maintaining proper emissions system operation and preventing diagnostic trouble codes related to the diesel particulate filter. As a genuine ACDelco GM component, it provides the same performance, reliability, and service life you expect from General Motors original equipment. ACDelco parts are specifically designed and validated for GM vehicles including Chevrolet, GMC, Buick, and Cadillac diesel models.
