A6805401817 Detroit EGT Sensor | ISO 16750-4 & SAE J1939-Certified Multi-OE Thermocouple for Aftertreatment Systems
AFTERTREATMENT SYSTEM OPTIMIZATION A6805401817 Detroit EGT Sensor SOLUTION
Precision-engineered as direct replacement for A6805401817 Detroit EGT Sensor and A6804910337 variants, this high-accuracy thermal monitor features quadruple-layer thermal shielding optimized for DD13/DD15/DD16 engines. The Inconel 718 alloy probe withstands continuous 850°C exposure in DEF dosing systems. Gold-plated signal terminals maintain ECU communication integrity across 2013-2024 model years.
Precision-cast M18x1.5 thread matches exhaust stack specifications. Anti-resonance housing provides vibration resistance for cross-country hauling. Multi-stage thermal barrier prevents signal drift in extended regen cycles.
