Walker Products Exhaust Gas Temperature Sensors (EGTS) are Genuine OE base sensors designed for accurate exhaust temperature monitoring in both gasoline and diesel engines. These sensors provide critical data to the engine control module (ECM) to support aftertreatment system functions such as DPF (diesel particulate filter) and GPF (gasoline particulate filter) regeneration, protecting components and ensuring emissions compliance. In diesel applications, EGTS sensors regulate DPF regeneration and help protect turbochargers and SCR systems. In modern gasoline applications, they monitor GPF temperatures to optimize regeneration cycles and prevent thermal overload. Each sensor is built to meet or exceed OE specifications for resistance, response time, and long-term signal stability. Constructed with high-temperature and corrosion-resistant materials, Walker EGTS units are engineered to withstand extreme exhaust conditions. Whether used upstream or downstream, these sensors deliver the performance, durability, and accuracy needed to support clean, efficient engine operation and emissions system integrity.
