NOx Sensor – Essential for Modern Emission Control

The NOx sensor is a central component of exhaust aftertreatment. It consists of
a probe and a control unit, is integrated into the exhaust system as a complete unit,
and detects nitrogen oxides (NOx) in the exhaust flow. Its use ensures compliance
with strict emission standards such as Euro 5 and Euro 6.

Areas of Application

  • Modern diesel vehicles with exhaust aftertreatment (e.g., SCR, LNT)
  • On-board monitoring and regulation of emissions

Operating Principle

  • Operation at high exhaust temperatures
  • Dual-chamber principle: NOx is catalytically split, and the resulting oxygen is measured
  • Signal transmission via CAN bus to the Engine Control Unit (ECU)

Technical Highlights

  • High-precision NOx detection under real driving conditions
  • Fast response time during dynamic load changes
  • Robust design for continuous operation at high temperatures
  • Integrated control unit for signal conditioning and diagnostics

Benefits

  • Reliable compliance with Euro 5/Euro 6 limits
  • Optimized exhaust aftertreatment (e.g., AdBlue dosing)
  • Reduced emissions and improved efficiency
  • High measurement accuracy ⇒ reduced need for recalibration
  • Quality replacement available in OE specification

Interfaces & Communication

  • CAN bus for data transmission to the ECU
  • OBD-capable status and error messages

Installation Instructions

  • Mount directly in the exhaust tract according to manufacturer specifications
  • Position thermally correct (observe heat protection)
  • Electrical connection to ECU/CAN network; check tightness and cable routing

Scope of Delivery

  • NOx probe with integrated control unit
  • Mounting hardware (model-dependent)
  • Installation and safety instructions


Note: Due to the high technical complexity and the required measurement accuracy,
the use of replacement parts in OE quality is recommended.

Description

This high-quality NOx sensor (A1038511) for Mercedes-Benz monitors nitrogen oxide levels in the exhaust system and, together with the SCR catalytic converter (AdBlue), regulates emissions in accordance with Euro 6 standards.

It operates reliably with a 12 V onboard power supply and delivers precise measurement signals to the engine control unit (ECU), ensuring compliance with emission limits and preventing fault messages (e.g. NOx efficiency errors).

Manufactured in OE quality: robust sensor technology with an integrated control unit, heat-resistant electronics, and corrosion-proof connectors ensure long service life even under high exhaust temperatures.

Installation is simple: loosen the old sensor, disconnect the connector, insert the new sensor and lock the plug; then clear any error codes and take a short test drive.

Technical notes: vehicle-specific connector and pre-assembled cable set; cable length and pin assignment comply with the OE specification of the listed references.

Compatible with common Euro 6 diesel engines on the Mercedes-Benz platform. Fast delivery and warranty included.

Matching OE numbers: A 000 905 85 11, A 000 905 97 03, A 000 905 01 08, A 000 905 28 09, A 000 905 26 19, 2064769.
