I started to have a look in the (long) DFI section of the service manual. It seems fairly evident that removing either or both switches will throw an error code once the ECU discovers that they're disconnected...

I believe that these are solenoid switches and the service manual does offer a DC resistance range for each switch:

Purge Valve (carbon canister, CAL): 30 - 34 ohms

Air Switching Valve: 20 - 24 ohms

I'm currently toying with the idea of substituting fixed resistors in place of the valves though I have not yet tested with them disconnected yet...

Also not certain what causes these valves to close or subsequently whether a lack of change in whatever condition warrants the valves to activate will cause another error code or DFI malfunctioning.

In any event, I'm leaving everything connected for now and will continue pursuing this once I have the Area P / Fuel Moto installed.

best,
