Unfortunately, I have a problem with my Lambda probe again, although it was exchanged only a few months ago for an original brand probe. I guess now a cable break and would like to know from you which values I have to measure. So far I have found here in the forum: (in brackets my measured value, all measured on the connection cable, so not on the Lambda probe!) A–> Mass 4-6V (4.3V) B–> Mass >5V (5.01V) C–> Mass >11V (12V) B–>D >100kohm (30kohm) Da ic h I’m not sure at the last value whether this is true at all, I wanted to ask you if there is a cable break or if I have measured it wrong. Otherwise: Can the Lambda probe give up its mind within a few months? Greetings
