Xulfiqar bhai I'm surprised as well. However I think you might be referring to a different fuse. This one was a little 10AMP fuse with EFI written on it. I checked out a wiring diagram that wasn't meant for Pakistani corolla but it did seem to resonate well with my car. In the diagram I noticed that the same wire powers up the Air Fuel Ratio Sensor (bank 1, sensor 1) however I didn't get a code about that for some reason. Anyway, I'm just glad that I was able to figure it out.
I just test drive the car and everything was okay. The check engine never came on. Also, the way I could tell that I have it fixed is because I started to get +ive voltage on one of the 2 terminals of the connector. I had been pulling my hair all day finding this exact current but finally...voila!
