2011649 New Aftermarket NOx Sensor fits DAF (24V, 890mm, Upstream) – GOTTO

Product Specifications:

The 2011649 is a heavy-duty, high-precision Nitrogen Oxide (NOx) Sensor (Aftermarket Replacement) engineered specifically for DAF Euro 4 and Euro 5 commercial vehicles. Positioned Before the Catalyst (Upstream), it continuously measures the raw engine-out NOx emissions to provide critical data to the vehicle’s ECU for precise AdBlue (urea) dosing. Featuring a precise 890mm cable length, this sensor ensures a direct physical fitment, preventing costly Limp Mode downtime and ensuring optimal SCR (Selective Catalytic Reduction) performance.

🌟 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.

👨‍🔧 Tech Notes & Installation Guide

• ⚠️ Critical Fitment Check (OE Number & Cable Length):

  Commercial vehicle exhaust layouts vary significantly. This specific Upstream sensor features an 890mm cable. To ensure correct fitment and ECU communication, you MUST verify that your original sensor’s OE part number matches 2011649, 1836060, 1793379, or Continental 5WK9 6628C before purchasing.

• ✅ Clear Fault Codes First:

  After installation, you MUST use an OBD diagnostic tool to clear all previous SCR/NOx fault codes stored in the vehicle’s ECU. Failing to perform this reset will keep the truck in Limp Mode.
