DINEX EMISSIONS INC NOx (Nitrogen Oxide) Sensor Inlet for Freightliner/Detroit EPA17 is engineered to restore accurate NOx measurement in aftertreatment systems used on Freightliner and Detroit diesel platforms. Designed as a direct replacement for OE inlet sensors, this unit measures nitrogen oxide concentrations upstream of the selective catalytic reduction (SCR) system to supply precise data to engine and aftertreatment controllers. Accurate NOx feedback enables the vehicle electronic control systems to modulate DEF dosing and exhaust aftertreatment strategy, reducing unnecessary reagent use while maintaining emissions performance targets. The sensor is factory-tested and validated for response and signal integrity, with mechanical and environmental protections to withstand typical service conditions in heavy-duty applications.
