Urea (DEF) Level & Quality Sensor Emulator
High-Spec Recovery for Cummins & Komatsu Tier 4 Final
 
The Cummins / Komatsu Urea Level Sensor Emulator is a professional-grade digital solution designed to replace faulty original equipment. Engineered for the high-vibration environments of Australian mining and construction sites, this module provides a high-fidelity signal to the Engine Control Unit (ECU), clearing "DEF Quality" and "Level Sensor" fault codes immediately.
This is a true Plug & Play solution utilising the industrial 4-pin Bayonet connector. Simply unplug the failing OEM sensor and connect the EMRT emulator to restore 100% engine torque and machine uptime.
