4 throttle blacktop MAP sensor valve

Hi to all,

I'm trying to understand vacuum line for 4 throttle. Btop throttle has this plastic container before go to map sensor. What is exact function of this thing? Is it check valve or reservoir?

I think is the filter to protect the map sensor ...

Surely it is not a valve. Map sensor will not work if there is a valve in it's vacuum line. It will be always full vacuum at map sensor.

I think it's more to dampening vacuum, so that map sensor not measure a fluctuating vacuum.

Yup, I believe that should be the filter for the MAP sensor.
