Method for monitoring lambda sensors |
摘要 |
A method for monitoring lambda sensors includes ascertaining a reference value from a magnitude of switching times under operating conditions of a lambda regulation cycle, in which a sensor signal changes from a rich value to a lean value or from a lean value to a rich value. A sensor is classified as functioning correctly if the reference value is less than an associated limit value.
