Back to Previous Page How does a Bosch NOx sensor function - NOx
The functional principle behind the NOx sensor is based on a ceramic electrochemical (amperometric double chamber) design. Exhaust gas passes over the sensing element, where selective electrochemical reactions measure concentrations of nitrogen oxides, oxygen, and even ammonia. The integrated Sensor Control Unit (SCU) processes these signals and communicates real-time data via CAN-bus to the ECU, enabling precise SCR dosing and emission control.
