Overview

PEX 193NOX2013 is a replacement nitrogen oxide (NOx) sensor for diesel exhaust aftertreatment systems. It is documented as interchangeable with Continental 5WK96765B, making it suitable for applications originally equipped with that reference. The sensor supports accurate NOx measurement in high‑temperature, high‑flow exhaust streams where dependable feedback is required for selective catalytic reduction (SCR) dosing and emissions compliance. Part of PEX’s German‑engineered aftermarket range, it is intended for demanding heavy‑duty environments.

Application and Interchange

Use 193NOX2013 wherever the system calls for Continental 5WK96765B and the installation requirements align with the original equipment specification. PEX positions its NOx sensors for both upstream and downstream locations around the SCR catalyst, supplying the control unit with the data needed to maintain target emissions performance and support diagnostics. Distributor listings confirm the cross reference but do not publish detailed electrical ratings, harness length, or pinout for this part; match by the 5WK96765B interchange and the vehicle’s OE documentation before installation.

Installation Guidance

Verify position (pre‑ or post‑SCR), connector style, and mounting arrangement against the removed unit. Follow OEM torque and handling procedures to protect the sensing element and wiring from heat and vibration. If the service procedure requires, perform any ECU adaptations or reset routines specified by the vehicle manufacturer to ensure accurate NOx readings and proper SCR control.
