Passat Variant 2009 - VW HVAC Air Quality Sensor - 3uga

Hi,
Looking for someone to help me delete the air quality sensor on a passat b6.
Usually the sensors I come across had positive, negative, and signal and can determine wich is wich on the wiring.
I need help with the values for this circuit or maive values of the sensor so I cand put a resistor on it and keep it at a fixed value.
The main problem I'm having is no heat. Climatronic apparently works ok. No errors on air flaps. Only error is the air quality sensor wich is reported as defective by vcds with no other details

Thank you.

I think you’ll be wasting your time . The air quality sensor does not affect heater performance.

Thank you,
That's what I was thinking. Wanted to eliminate the easiest things on the list.
Guess I'll be getting the hose and start unpluging the interior radiator

Thank you
