NOx Sensor – Essential for Modern Emission Control

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

Applications

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

Operating Principle

• Operates at high exhaust temperatures
• Two-chamber concept: NOx is catalytically split, 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 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 aftertreatment (e.g., AdBlue dosing)
• Lower emissions and improved efficiency
• High measurement accuracy ⇒ reduced recalibration needs
• OE-spec replacement parts available

Interfaces & Communication

• CAN bus data transfer to the ECU
• OBD-capable status and fault messages

Installation Notes

• Install directly in the exhaust line per manufacturer guidelines
• Ensure proper thermal positioning (heat shielding)
• Connect to ECU/CAN network; check sealing and cable routing

In the Box

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

Note: Due to the sensor’s complexity and accuracy requirements, we recommend OE-quality replacement parts.
