5WK97403 | Genuine Detroit Diesel® Nitrogen Oxide Sensor

Description and Purpose:

The Nitrogen Oxide Sensor is a Genuine emissions control component designed for high-efficiency monitoring of NOx levels in selective catalytic reduction (SCR) systems. Part Number: 5WK97403. Condition: New. Brand: Detroit Diesel. Operating at 12 volts and featuring an 18-inch cable, this sensor ensures precise feedback to the engine’s control module for accurate DEF dosing and optimized exhaust treatment. Its robust design is compatible with DD13 and DD15 engines, providing dependable emissions data even under extreme temperature conditions from -40 to +115°C.

Why Replacement is Important:

Over time, NOx sensors degrade due to heat exposure and exhaust contaminants. Failure to replace a faulty sensor may lead to emission errors, power loss, or SCR malfunction, compromising environmental compliance and vehicle performance.

Impact on Vehicle Performance:

A properly functioning NOx sensor helps maintain correct DEF injection rates, improves fuel efficiency, and ensures continued adherence to emissions standards. It also prevents unplanned downtime and costly aftertreatment system repairs.
