So, my car stopped working a long while ago, and I have been slowly trying to fix it. We figured out that the #10 fuse was blown, so we changed it and it starting working again! But, it keeps blowing that fuse. My check engine light was on, so I plugged in a code reader and only got one code for an Inlet Air temp sensor.

So we changed that and also put 1 litre of oil in it because it has been sitting for quite a while, and it took right off. I am planning on getting an oil change done on it today since it was sitting for so long. I drove it to work and the check engine light is off now and everything seemed fine, until the fuse blew again! When it blew, the oil light came on and I lost all power steering and my engine was off.

My lights and the radio were still on, but I couldn't do anything, so I changed the fuse since I had extras, and parked it at work. I am at a loss of what it could be, the only thing I can think of is electrical, maybe a wire somewhere. Please help.

Where is the fuse located, under hood fuse block, interior fuse block? What is the fuse amp rating? I'd have to look at wiring diagram and see what circuits are controlled by that fuse. Go from there.

The fuse is interior and 15 amps. I am going to check all the wiring and see if I can find a short. There are no error codes for the car and the engine light isnt on, so this is the only other thing I can thing of :(

Note the diagram. Get at the splice and disconnect/replace one at a time, if the fuse blows quickly, hopefully that will show which circuit is causing the problem, maybe that will narrow it down a little.

Like hunting a needle in a haystack. Unplug the air temp sensor, see if it will stop blowing the fuse? Also, after the fuse blows, see if there is ref voltage at sensor that uses ref voltage, key on.

The problem could be a bad wire on backside of fuse block?
