Application and OE Replacement

The PEX 193NOX2014 is a nitrogen oxide (NOx) sensor for heavy-duty exhaust aftertreatment systems. It is presented as a direct replacement for the Continental 5WK97339A sensor and is described by resellers as suitable for selected Detroit Diesel engine applications that originally specified the equivalent Continental unit. Supplied as a complete exhaust sensor assembly, it is intended for use in the aftertreatment stream rather than as an internal engine component.

Installation and Compatibility

This sensor is described as plug-and-play, matching existing connectors and mounting locations on compatible vehicles to simplify service and minimize downtime. Designed to integrate with the vehicle’s aftertreatment control strategy, it reports NOx concentrations for emissions management. Because public listings do not publish detailed electrical ratings or dimensional data for this part, verify the OE reference (5WK97339A) and harness/connector compatibility before ordering.

Performance and Build

PEX NOx sensors are engineered in Germany using high-grade materials for demanding heavy-duty environments. Emphasis on fast response and durable construction supports accurate NOx feedback to the SCR system, helping maintain stable dosing control and reliable emissions performance. For fleets seeking a proven aftermarket alternative to the original sensor, 193NOX2014 delivers the fit and function required for service replacements on applicable Detroit Diesel platforms.
