the 60 amp will do fine, but if you ever had an overvoltage or a short, the ECU could fry, or a wire could cook and melt causing a fire, go with whats rated, put in the 20 amp fuse.

Ok, just put the old MAF in with the screen, and reset the ECU. CEL is gone, I'm letting it run for 15 mins. I can't drive it anywhere till later.

One thing I found odd is that when I pulled the fuse for the ECU, it was a 60 amp fuse, while on the diagram on the fuse box cover it's pictured as a 20 amp fuse. Would that make a difference to anything, or should I not worry too much about it?

Worry about it. change the fuse immediately. It's there for your safety.

Dude, that's bad advice. If you remove the first 7 words, it becomes good advice.


Fire or loss of life are the worst thing that can happen in electronics. An incorrect fuse can cause both. The fuse is there to protect the wire. The wires will most likely fry at 25A. this will cause a fire along the length of the wire. That's your engine bay and cockpit. Normally a fuse will blow and you can correct the problem. If the fuse does not blow because it's too high of power, then you can get shocked and die. It only takes 1 A to kill you. Think about how many extra amps you're allowing to pass through that wire in case of a fire. Fuses are a safety device, if they pop, they did their job. Never upgrade a fuse.

Ok, well that's great to hear, cause this fuse has been in there since I've had the car. I wanna know who put it in and why. That's BS. Changing it now, as soon as I finish swapping my steering wheel.

technically it is good advice. a fuse is a fail safe, so saying that it will do fine, makes sense. like she said shes had it in for years, lucky? yea probably. as long as theres no electrical failure, simply having the wrong fuse in is fine. if you should so happen to crash your whip and bend some metal into a wire causing a short, or damage an electrical sensor causing a short, and the wrong fuse fails to pop due to the short, then having a wrong fuse in, is not fine. !

No, it's bad advise. Wires are rated for a certain amount of juice, and the fuse is likewise rated. Put too much juice through, and the fuze is too high so it doesn't blow, you get a FIRE, or blown electronics.

DTN is right.

no sir, doesnt matter wat fuse is in there... ...as long as you dont "put to much juice through" I wasnt saying that the wrong fuse is ok, just that the wrong fuse will still do the job that the circuit needs, until there is some sort of circuit failure.

how many pages can you guys get this thread up to as we all argue the same point?

It won't go onto further pages, because you won't post in here again after I do.

Clear?


It's simple. Fuses are there to keep you from putting too much juice through to protect wire, components, and ultimately, the vehcile and lives. You put a fuse in there larger than stock, and too much power can get through, causing those problems. You have no other way of ULTIMATELY controlling the "juice", than using the fuse. Shit happens, spikes, power surges, what have you.

Perfect example. My window relays keep blowing a fuse. Will I put in a higher amperage fuse? No.

Why? I don't want to replace half the wiring in the car.

Simple.

Either way, I changed the fuse. Im a little disturbed that it was even in there to begin with.
