Method for adjusting a pressure sensor in an SCR system

A method for adjusting a pressure sensor of an SCR system between a delivery pump and a dosing valve, with which the delivery pump is switched off during a switch-off phase of the SCR system and a pressure (pm) measured by the pressure sensor is detected at least during a section of the switch-off p...

Beschreibung
Zusammenfassung:	A method for adjusting a pressure sensor of an SCR system between a delivery pump and a dosing valve, with which the delivery pump is switched off during a switch-off phase of the SCR system and a pressure (pm) measured by the pressure sensor is detected at least during a section of the switch-off phase in which the delivery pump is switched off, and the adjustment of the pressure sensor is carried out by using the measured pressure (pm) as the reference pressure for the pressure sensor.
