New Nox Sensor Line Released for Detroit DD15 and DD13 Engines

We are proud to announce the release of our latest Nox Sensor series, engineered to deliver accurate, reliable nitrogen oxide monitoring for heavy-duty diesel engines. This new range covers four high-demand OE reference numbers — EA0111534028, EA0101531928, RA0101538128 and EA0101532228 — and is specifically developed for Detroit DD15 and DD13 engine platforms.

Why the Nox Sensor Matters

The Nox (NOx) sensor is one of the most critical components in modern diesel after-treatment systems. It continuously measures the concentration of nitrogen oxides in the exhaust stream and reports this data to the engine control unit (ECU). Based on these readings, the ECU precisely controls Diesel Exhaust Fluid (DEF) dosing and Selective Catalytic Reduction (SCR) performance. A healthy Nox sensor therefore delivers three major benefits:

• Emissions compliance: Keeps vehicles within Euro and EPA NOx limits, avoiding fines and failed inspections.
• Fuel and DEF efficiency: Optimized dosing reduces unnecessary DEF consumption and improves overall fuel economy.
• Engine protection: Prevents derate events, warning lights and costly downtime caused by faulty after-treatment readings.

Because the sensor sits directly in the exhaust flow, it is exposed to extreme heat, soot and chemical contamination. Over time, a worn sensor can drift out of calibration, triggering fault codes such as P2201 or P229F, increasing DEF usage and reducing engine power. Replacing a degraded sensor with a high-quality unit is the fastest way to restore full performance and compliance.

Product Highlights

Key Features

• Direct OE cross-reference fitment for EA0111534028, EA0101531928, RA0101538128 and EA0101532228.
• Compatible with Detroit DD15 and DD13 heavy-duty diesel engines.
• High-precision ceramic sensing element for fast response and stable readings.
• Heat- and contamination-resistant construction for long service life.
• Plug-and-play installation with factory-style connectors — no reprogramming required.
• 100% tested before shipment to ensure reliable CAN communication with the ECU.

Fitment and Applications

This new Nox sensor series is purpose-built for the Detroit DD15 and DD13 engine families, which power a wide range of Class 8 trucks, vocational vehicles and buses across North America. Whether you operate a long-haul fleet, a repair workshop or a parts distribution business, stocking these four OE numbers ensures you can service the most common NOx sensor failures quickly and confidently.
