Reviving a Pierburg Mass Air Flow (MAF) sensor with an adapter connector?

Hi.

I am referring to this article.
Okay, I'm ready. Please provide the German text you want me to translate.

Ulf is writing that you can solder a 22 kOhm resistor between the outer pins to lower the reference voltage.

Can this also be done with the +5V and "sensor output" pins using a pull-up configuration?

Then you wouldn't need to remove the mass airflow sensor (MAF), but instead you could build an adapter plug that would modify the value accordingly.

Is that possible?

I wouldn't try that (unless it's on an LLM that's already beyond saving).

If the device has an output similar to that of an amplifier, with low impedance (which I believe is the case), any attempt to distort the output signal would be practically nullified – only the overall power consumption would increase.
The whole thing would probably work with a slightly lower voltage setting, but eventually something would likely burn out.
