Useful Information

Description and Purpose:

This New Genuine International / Navistar DEF Quality & Level Sensor Head, Part number: 4254214C91, tracks DEF purity and tank volume in 12-gallon systems. Using a digital canbus sensor through a Deutsch DT4 connector, it integrates suction, return, heated 5/8 ports, and a 40µ filter through a 6-bolt interface for reliable flow and accurate SCR monitoring.

Why Replacement is Important:

Incorrect purity or level signals cause derates, reduced DEF dosing, and active fault codes in emission systems.

Impact on Vehicle Performance:

Stable readings retain proper SCR function, preventing derates and maintaining engine power under emission regulations.

Manufacturer Information:

International® builds components specifically for demanding commercial use, delivering reliable operation through extended hauling and harsh driving environments.

Navistar® develops systems designed to support long-distance fleet operation, ensuring dependable functionality and reduced downtime.
