It’s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.

A compressor and condenser turn gas into liquid, and an evaporator converts it back into gas, while absorbing heat from the CPU chip and other components. Phase change cooling creates subzero ...
