No “good climate” in the car

Dear elk friends, since my air conditioning system (despite new capacitor + filling) is not working, I was at the Bosch Service today to let the error memory be read out. My fear (climate compressor) fortunately did not come true, but with the diagnosis: air conditioning pressure sensor: signal implausible I can’t do anything. Do you have any idea what this might mean? Thank you very much in advance Pappnase1
