Default New Genuine Volvo Maf sensor same old tests?

Does anyone have any experience with the new Genuine Volvo MAF sensors with P/N 8251497 that are supposed to be a direct replacement for the Bosch 0 280 212 016?
I was wondering if the same Bentley manual tests apply to these new units when diagnosing the sensor because I'm on my 2nd unit from FCPeuro and both seem to be faulty according to the bentley tests for LH-2.4 as well as my old Bosch maf working perfectly when swapped out with these new maf sensors I've ordered on the car.

The reason I'm asking is because the bentley manual says pins 2 and 3 on the sensor should have 2.5-4 ohms but both of the new Volvo sensors show no continuity and infinite resistance unlike my Bosch sensor which shows 3.0 ohms just as the bentley suggests. My car stalls out everytime with the new Genuine Volvo sensors but drives fine with each Bosch maf I have.

Any insight? Is there something im missing with the new sensor that replaced the old Bosch part such as a different harness or something more in depth im supposed to replace with the new sensor? The pins don't seem do do the exact same things as the Bosch sensors pins. My car is a 1992 240 DL B230f N/A.

Thank you
