Useful Information

Description and Purpose:

The Genuine International DEF Tank QLS Sensor Head, Part Number: 5012172R91, is an OEM emission control component in New Condition. Designed specifically for use in 9.5 Gallon DEF tanks, this sensor head plays a vital role in monitoring fluid levels and communicating accurate DEF data to the vehicle’s system. Built for commercial trucks operating under severe service or linehaul duty, it ensures the proper functioning of SCR systems required for EPA compliance.

Why Replacement is Important:

A failing sensor head may result in incorrect DEF readings, which can lead to emission faults, dashboard warnings, and reduced engine power. Timely replacement avoids regulatory violations and costly operational delays.

Impact on Vehicle Performance:

Reliable DEF monitoring maintains optimal dosing in the aftertreatment system, helping the engine run efficiently, lowering emissions, and preventing power loss in high-demand conditions.

Manufacturer Information:

International® trucks incorporate ergonomic design and innovative driver assistance systems to improve safety and reduce fatigue during extended routes.

Navistar® trucks offer robust powertrains and chassis built to withstand challenging road conditions and heavy freight loads.
