Purge Solenoid Valve - It operates the fuel tank purge canister. I have mine disconnected cause it failed. Works fine but drops a DTC (Diagnostic Trouble Code) in the ECM (Electronic Control Module (Scion Manuals call it this instead of ECU)). I believe that the line with the green capped vacuum connection goes to the canister. The other PSV port goes to the TB (Throttle Body).
