This MAP Bypass Valve completely blocks boost from reaching your MAP sensor, thus simulating a wide-open-throttle reading at the vehicle's ECU. The vehicle is then prevented from running in "limp" mode so that no check-engine light appears. The end result is protecting the MAP sensor from being damaged.
