摘要 |
A method for processing measured values two nitrogen oxide sensors, one of which is arranged upstream of a nitrogen oxide reduction catalytic converter in the exhaust gas system of a motor vehicle and the other of which is arranged downstream of the nitrogen oxide reduction catalytic converter, involves recording and comparing measured values from the two nitrogen oxide sensors at least approximately at the same time. A sensitivity of the first nitrogen oxide sensor and/or of the second nitrogen oxide sensor is changed depending on the result of the comparison. |
