Is the black rubber hose behind the air filter box disconnected from the metal tube that it attaches to? This is a common problem and happens when someone checks the air filter. Pull the EFI fuse to reset the light.

Try already to pull out the EFI fuse and put it back, the lights off for a few seconds only and lights come back again. Pls, if there's any other way to solve this problem.
