MAF Wiring Trace Looking for a wiring diagram that shows the route and if the MAF sensor wires tie into anything else prior to getting to the PCM. Or if anyone knows this off hand.
Im not getting MAF reading (code 48) to the PCM, and I keep popping the 20Amp fuse in the box by the headlight labeled 'engine sensor'. Thinking a wire might have been crossed somewhere.
Also would be helpful to understand what all is powered through that 'engine sensor' fuse thats in the fuse box under the hood.
These electical problems are a pain!

You should probably include more info on your car. Your sig says 96, but the code you referred to is not an OBD-II code. Do you have an OBD-I conversion? Still the 1996 engine harness? Do you have headers? A4 or M6? Your mods should be in your sig.
The most common cause of that fuse blown is O2 sensor wires burned up on headers.
