My car doesn't start anymore now cuz I've put a new fuse on my subwoofer amplificator but I forgot to disconect the battery so it does a ''short''...(because the positive is connected directly to the battery)And now my car is throwing a code...: 12 - Mass Air Flow Meter Sensor !
I tried my friend's m.a.f., no succes... IF IT'S THROWING A CODE IT'S BECAUSE THERE'S A BLOWN FUSE OR A CUT WIRE BUT THERE'S NO FUSE ON THE M.A.F. SO IT'S SUPOSED TO BE A WIRE ?...? Can any other thing throw me a code or it's 100% sure it's a wire to the MAF ???
P.S. My car is a '93 240SX SE...

Sounds to me like you blew the fuseable link on the back of the positive batt. cable. It's a green box located right at the terminal. Had a problem with my Pathy where the lights wouldn't come on after a stereo install and like you I forgot to remove the positive cable. Not so severe as your problem, but the Pathy has two links, while a 240 has only one. I blew the secondary link.
