Question Continually blowing fuses
Ever since I put JDM exhaust on my 01 L, I keep blowing the #23 HEGO sensor fuse. What is the HEGO sensor and why does that fuse keep blowing?

blowing fuses
The fuse is blowing most of the time when I have accelerated hard and then let off. When letting off the accelerator is when the fuse is blowing.

Check for a broken wire. My brother's truck did the same thing. Broken wire, new O2 sensor fixed it. -Mat-

I'm assuming you installed JDM's headers...........here is pic that shows how the sensor wire should be placed:
