just started last week, car does not run any different. Fuel mileage seems fine, cleared the codes and they came right back.

1. p0100-maf or vaf a circuit malfunction
2. p0078-intake valve bank 1 control circuit
3. p2401-evap system lk detect pump ctl circuit low
4. p2420-evap system switching valve ctl circuit high
5. p0458-evap system canister purge sol circuit low

cleaned the engine and chassis grounds. looked at the evap canister, everything looks fine. replaced the fuel cap with factory cap. called the dealer and all the recalls were performed on the car. I traced it down to a blown fuse for the engine management. I replaced the fuse and it popped right away. anyone know where the ground for evap system switching valve would be?
