Basically it holds the butterfly in the pipe open and "tricks" the sensor into thinking its working normall so you dont get the warning light.
You can get a switchable one as well.

If you pick one up, email me and I will send an english version of how to install it

There is no function available with the SEPST to disable it. If you just remove it then you will get a code on the speedo. You need an eliminator plug that fits into the harness where you remove the valve motor.
