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

Excerpt from the TecDoc assignment for this variant.
These reference numbers help compare the removed part.
This high-quality NOx sensor (A1070980) for PSA (Peugeot/Citroën) monitors nitrogen oxide levels in the exhaust system and, together with the SCR catalyst (AdBlue), controls emissions in accordance with the Euro-6 standard.
It operates reliably with a 12 V onboard power supply and provides precise measurement signals to the engine control unit (ECU), ensuring compliance with limit values and preventing error messages (e.g. NOx efficiency).
Manufactured in OE quality: robust sensor technology with integrated control unit, heat-resistant electronics, and corrosion-proof connectors ensure long service life even at high exhaust temperatures.
Installation is straightforward: loosen the old sensor, disconnect the plug connection, insert the new sensor and lock the connector; then clear the fault codes and carry out a short test drive.
Technical notes: vehicle-specific connector, pre-assembled wiring harness; cable length/pin assignment correspond to the OE specification of the listed references.
Compatible with common Euro-6 diesel engines of the PSA (Peugeot/Citroën) platform.
Fast delivery and warranty included.
Matching OE numbers: 9821120980, 9678570780, 3637852, 39168189, 22827995, 7422827995.
