Useful Information

Description and Purpose:

OEM DEF Tank Level Sensor by International / Navistar. Part Number: 4097727C91. Condition: New. This heavy-duty truck component is designed to precisely measure the Diesel Exhaust Fluid level inside DEF tanks of 15.5, 16, and 23 gallons capacity. Using advanced QLS and SSI sensor technology, it provides continuous, accurate fluid level data that is essential for the Selective Catalytic Reduction (SCR) system to function properly. By monitoring DEF levels in real time, this sensor helps prevent emissions violations and ensures the truck’s aftertreatment system operates efficiently, protecting both engine performance and environmental compliance in commercial vehicles.

Why Replacement is Important:

Replacing a faulty DEF sensor prevents incorrect fluid readings that can trigger emission faults, engine derates, or system shutdowns. Maintaining sensor accuracy protects your truck from unexpected downtime and regulatory issues.

Impact on Vehicle Performance:

Accurate DEF level sensing supports steady SCR function, preventing power loss or engine shutdown caused by emission system errors, thus keeping commercial vehicles running smoothly.

Manufacturer Information:

International® is a leading manufacturer of commercial trucks built for durability, performance, and fleet efficiency across multiple industries.

Navistar® produces commercial trucks and engines engineered for reliability, fuel efficiency, and compliance with emissions regulations.
