Cummins 4384568 Exhaust Gas Temperature Sensor

The Cummins 4384568 is an exhaust gas temperature (EGT) sensor designed for Tier 4 emissions compliant 6.7 liter ISB and QSB diesel engines. It features a four-probe thermocouple construction to provide precise temperature data to the engine control module (ECM) for selective catalytic reduction (SCR) and diesel particulate filter (DPF) regeneration management. The sensor operates on 12V or 24V electrical systems and is engineered to withstand extreme exhaust gas temperatures up to 900°C. This component serves as a direct OEM replacement for Cummins part number 4384568 and cross-references to OE number A054U495. It is compatible with aftermarket equivalents including Dinex 5EL075 and Skyline STE086. Application coverage includes on-highway medium duty trucks and off-highway equipment powered by Cummins B6.7, ISB 6.7L, and QSB 6.7L engine platforms meeting EPA17 emission standards.
