Efficient emission control for your truck

Exhaust gas sensors and probes are crucial for the precise measurement and control of emissions in modern truck exhaust systems. They continuously monitor parameters such as nitrogen oxide (NOₓ) concentrations, oxygen content and exhaust gas temperature to optimize the performance of the exhaust gas aftertreatment system. Thanks to their precise data acquisition, they enable efficient control of AdBlue® dosing and thus contribute to compliance with legal emission regulations.

High-quality spare parts for exhaust gas sensors & probes

Our range includes a variety of NOₓ sensors, lambda probes, temperature and pressure sensors for various truck models. These components are precisely manufactured and tailored to the specific requirements of modern exhaust systems. They ensure reliable monitoring and control of emissions, resulting in improved engine performance and reduced emissions.

Sensor

What should you look out for when buying:

SENSORART

Determine whether you need a NOₓ sensor, a lambda sensor or a temperature/pressure sensor, depending on the specific function in your exhaust system.

INSTALLATION POSITION

Check whether the sensor must be installed before or after the catalytic converter or particulate filter, as the measured values may vary depending on the position.

MANUFACTURER INFORMATION

Observe the OEM part numbers and reference numbers to select the correct component.

Expert Guide: Everything You Need to Know About Truck Sensors & Probes

They continuously measure parameters such as NOₓ concentration, oxygen content, exhaust gas temperature, and pressure. The engine control unit uses this data to precisely control combustion and exhaust aftertreatment and to ensure compliance with emission limits.

The NOₓ sensor measures the nitrogen oxide concentration in the exhaust gas, the lambda sensor measures the residual oxygen content, the temperature sensor measures the exhaust gas temperature, and the pressure sensor measures the differential pressure (e.g., across the particulate filter). Each type of sensor provides the control unit with different, yet equally essential, information.

The NOₓ sensor measures nitrogen oxide levels before and after the SCR catalyst. Based on these readings, the control module calculates the exact amount of AdBlue® required. A faulty sensor results in incorrect dosing, poorer emissions, and often error messages.

Typical signs include an illuminated engine or exhaust warning light, stored error codes, a loss of power (limited performance), increased AdBlue® or fuel consumption, and a failed emissions test.

The readings vary depending on the sensor’s location—before or after the catalytic converter or particulate filter. A sensor installed in the wrong location or one that has been mixed up with another will send implausible values to the control module and trigger error messages.

Sensors and probes are wear-prone and precision components. If they become worn, fouled with soot, or develop an internal defect, they generally need to be replaced, as attempts to clean them can damage the sensitive measuring elements.

The key factors are selecting the correct sensor type, choosing the proper installation position, and verifying compatibility using the OEM part number and common equivalent part numbers. This is the only way to ensure that the sensor is compatible with your vehicle’s control module.

We carry NOₓ sensors, lambda sensors, and temperature and pressure sensors in OE quality for all major brands, including MAN, Mercedes-Benz, Scania, Volvo, DAF, and Iveco.
