51154080031 New Aftermarket NOx Sensor fits MAN (24V, 615mm, Upstream) – GOTTO

Product Specifications:

The 51154080031 is a heavy-duty, high-precision Nitrogen Oxide (NOx) Sensor (Aftermarket Replacement) engineered specifically for MAN Euro 6 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 615mm 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 a 615mm cable. To ensure correct fitment and ECU communication, you MUST verify that your original sensor’s OE part number matches 51154080031 or Continental A3C00370800 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.
