Vitesco Technologies NOx sensors: OEM supply for SCR systems
Vitesco Technologies — formerly Continental Automotive — is one of the primary OEM suppliers of NOx sensors to the commercial vehicle industry. Their sensors are fitted as original equipment to vehicles from MAN, DAF, Iveco, and Cummins, among others. When a NOx sensor on one of these vehicles requires replacement, a Vitesco sensor is the direct OEM-equivalent replacement without the calibration uncertainty of a non-specified aftermarket unit.
The NOx sensor measures nitrogen oxide concentration in the exhaust stream both upstream and downstream of the SCR catalyst. These two readings allow the engine management system to calculate the correct AdBlue dosing rate, verify that the catalyst is converting NOx at the required efficiency, and identify SCR system tampering. When either sensor fails, the system loses this reference data and fault codes for dosing system errors or catalyst efficiency follow.
Vitesco NOx sensors use a specific calibration constant that is programmed into each sensor during manufacture. Using a sensor with a different calibration produces ongoing dosing errors even if the sensor is electrically functional. This is why fitting a genuine Vitesco part number — verified against the application — is the correct approach rather than substituting a generic NOx sensor of the same connector type.
Confirm the OE part number from the original sensor before ordering to ensure the correct calibration for your specific engine variant.

Frequently asked questions
What vehicles do Vitesco Technologies NOx sensors fit?
Vitesco Technologies is an OEM supplier of NOx sensors to MAN, DAF, Iveco, and Cummins applications among others. Always confirm the part number against the original sensor on the vehicle before ordering — NOx sensors are engine and position-specific, and the same connector type can carry different calibrations for different applications.
What is the difference between an upstream and downstream NOx sensor?
The upstream NOx sensor measures NOx concentration entering the SCR catalyst. The downstream sensor measures the NOx that has passed through the catalyst. The ratio between the two readings tells the engine management system how efficiently the catalyst is operating. The two sensors have different calibration constants and are not interchangeable.
How do I find the correct Vitesco NOx sensor part number?
The most reliable method is to read the part number directly from the existing sensor on the vehicle. Alternatively, call us on 01527 68279 with the chassis number and engine code and we can confirm the correct part number before you order.
Do Vitesco NOx sensors require coding after replacement?
On most applications, fault codes must be cleared via a diagnostic scan tool after replacement to confirm the system is operating correctly with the new sensor. Some makes may require a specific adaptation reset.
