Mesaurements on MAP -sensor type 3 wurde erstellt von Göran
Hallo !

I know that there is two coils in the sensor.
Primary is 90 Ohm and secondary 357 Ohm.
I have with a vacuumpump tested so it looks like the leakage rate is ok .
Now my question:
Should the resistans in the coils change value depending on the pressure into the MAP ?
Or what is it for signals that ECU wants from the MAP ?

Hi Göran (your name, I think...)
Welcome to the forum.
No, the sensor doesn't change resistances depending on the vaccum level.

You find the information you ask for in Volker's compendium: https://oldtimer.tips/en/d-jetronic/mps
Don't blow into the sensor. It is a vacuum device and could get damaged..

Regards
Norbert
