The 5801754016 is a heavy-duty, high-precision Nitrogen Oxide (NOx) Sensor (Aftermarket Replacement) engineered specifically for the upstream (inlet) position of Iveco (Stralis, Eurocargo, Trakker) Euro 6 commercial vehicles equipped with FPT Cursor engines. Manufactured to meet rigorous OEM protocols, it accurately measures NOx concentration in the exhaust gas before it enters the catalytic converter. This ensures optimal SCR (Selective Catalytic Reduction) system performance, restores proper engine function, and prevents costly Limp Mode / torque derating downtime. Designed for a direct fit to get your fleet back on the road.

🌟 Premium Engineering Features:

• Proprietary Core Chip: Equipped with an in-house developed sensing chip, ensuring strict quality control from the source to the final product.

• Superior Accuracy & Stability: Delivers highly stable signals with strong anti-interference capabilities, guaranteeing precise NOx readings even in the harshest exhaust environments.

• Ultra-Fast Response: Instantly communicates with the vehicle’s ECU to regulate urea (AdBlue) injection rapidly, preventing emission-related derating.

• Extended Service Life: Built with premium, durable materials designed for long-term reliability and wide-range detection of varying NOx concentrations.

👨‍🔧 Tech Notes & Installation Guide

⚠️ The Logical Isolation Wall (Critical Fitment Check):

Euro 6 SCR systems require strictly paired sensors separated by a logical isolation wall. This Upstream (Front) sensor CANNOT be swapped with its downstream counterpart. Upstream and Downstream control modules have opposite internal chip communication baud rates and pinout definitions. Plugging them into the wrong position will result in immediate ECU failure recognition and keep the truck in Limp Mode.

💰 Why Replace the Front & Rear Pair?

• The Risk: Upstream and downstream NOx sensors operate in the exact same harsh exhaust environment. If this upstream 5801754016 has failed, the downstream sensor is statistically at the end of its lifespan, risking a secondary breakdown.

• The Fix: Take advantage of our Bundle Discounts to replace both sensors simultaneously. This maximizes truck uptime and significantly reduces repeated labor and diagnostic costs.

✅ Clear Fault Codes First:

After installation, you MUST use an OBD diagnostic tool to clear all previous SCR/NOx fault codes stored in the ECU to exit Limp Mode.

The 5801754014 is a heavy-duty, high-precision Nitrogen Oxide (NOx) Sensor (Aftermarket Replacement) engineered specifically for the downstream (outlet) position of Iveco (Stralis, Eurocargo, Trakker) Euro 6 commercial vehicles equipped with FPT Cursor engines. Manufactured to meet rigorous OEM protocols, it accurately measures NOx concentration at the SCR outlet to verify catalyst efficiency. This ensures the exhaust gas meets strict emission standards, maintains optimal selective catalytic reduction performance, and prevents costly Limp Mode / torque derating downtime. Designed for a direct fit to get your fleet back on the road.
