Car keeps blowing the EMS2 why??

EMS 1 is designated to engine management.

What’s not working about the vehicle since this problem has occurred?

It's throwing codes PO340, PO660, PO458, and PO403 all involving the circuit... I unplugged behind the brake pedal and its still blowing the EMS2

After further research (on your behalf) - sedan is different from hatchback: EMS2 - LEGR Valve, HO2S, EVAP Canister Purge Solenoid, CMP Sensor Complete reversed for some odd reason - whatever! Now - the codes you posted involve the canister purge solenoid and camshaft position sensor - which is listed above as you can see, We have no idea and can’t even guess as to where the short to ground is going to be located .. That said - it is very possible to have a sensor shorted internally - can try disconnecting wiring connectors however the short circuit can be located at any point within the particular failed circuit. It is going to take time and familiarity with troubleshooting this type failure to discover the actual culprit. Without personnel *hands-on* testing - that’s all the ammo I have. Good luck!

Can use a 12 volt test light instead of blowing a bunch of fuses - test light should NOT light if used in place of the fuse - test light clip to one fuse terminal - test light point to the other fuse terminal.

Do I unplug it behind the pedal and see if it still blows??
