2294291 New Aftermarket NOx Sensor fits Scania Euro 6 (24V, Downstream) – GOTTO

Product Specifications:

The 2294291 is a heavy-duty, high-precision Nitrogen Oxide (NOx) Sensor (Aftermarket Replacement) engineered specifically for the downstream position of Scania Euro 6 commercial vehicles. Manufactured to meet rigorous OEM protocols, it accurately measures NOx concentration at the SCR outlet. This ensures the exhaust gas meets 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.

🌟 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

💰 Why Replace the Front & Rear Pair?

• The Risk: Upstream and downstream NOx sensors operate in the exact same harsh exhaust environment. If your downstream 2294291 has failed, the upstream sensor is statistically at the end of its lifespan, risking a secondary breakdown and repeated Limp Mode.

• 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 installing the new 2294291 NOx sensor, you MUST use an OBD diagnostic tool to clear all previous SCR/NOx fault codes stored in the ECU. Failing to perform this reset will prevent the vehicle from exiting Limp Mode.

⚠️ Critical Maintenance Step:

A failed NOx sensor is frequently a symptom of underlying SCR blockages. Always inspect the AdBlue/DEF doser and exhaust pipes for severe soot or urea crystallization buildup before installing the new sensor to prevent immediate contamination and premature failure.
