Hey there,of course I do,because I´m from Munich,Germany
Well,these words are hard to translate,even for my online dictionary which knows a lot of engeneering words.
Drosselklappenpotentiometersignal : Means the Throttle Body potentiometer signal (perhaps the short form is TPS,I don´t know)
Drehzahlsignal : Means RPM signal,you´re right
Klemme 15: yes,clamp or clip
Masse: I´m not quite sure,but this is an electronical think,an "Masse" means normally GND (connecting cable to ground or something like that).I´m pretty sure that this has nothing to do with 02 !
Luftmengenmesser: Yes,it´s airflow meter
Versorgungsspannung: supply voltage
I hope I could help you (or prove what you found out),if you got more questions,feel free to ask.
But to get sure that I reach your message,write an E-Mail at
Overkill1990@gmx.de because I´m not here so often.
best regards,Moritz
