Useful Information

Description and Purpose:

The Genuine DEF Tank Level Sensor is a component designed to provide accurate and reliable measurement of Diesel Exhaust Fluid levels in tanks ranging from 15.5 to 23 gallons. Part Number: 4086805C91. Brand: International. Condition: New. This sensor employs advanced QLS SSI technology to ensure precise fluid level monitoring, which is essential for the proper functioning of SCR (Selective Catalytic Reduction) systems in heavy-duty commercial trucks. By delivering real-time data on DEF levels, it helps prevent system errors and supports efficient emissions control.

Why Replacement is Important:

An inaccurate or malfunctioning DEF sensor can cause incorrect DEF readings, triggering emissions system faults or vehicle shutdowns. Replacing the sensor promptly maintains emission compliance and avoids costly downtime or repairs.

Impact on Vehicle Performance:

Precise DEF level sensing allows the SCR system to dose the fluid correctly, reducing nitrogen oxide emissions and optimizing fuel consumption, which is vital for maintaining the performance and environmental standards of commercial trucks.

Manufacturer Information:

International® manufactures durable commercial trucks engineered to deliver reliable performance, advanced safety features, and optimized fuel efficiency for diverse fleet operations.

Navistar® designs and manufactures commercial trucks and engines focused on durability, fuel efficiency, and advanced emissions technology for demanding fleet applications.
