Hey everyone, just joined today and BEFORE you flame. I have been reading on issues about the common culprit of blown fuse 15 (under-dash) 7.5 AMP fuse. I AM STUMPED! I removed my Intake Manifold bracket, looked around for any sign of corroded, burnt, and/or chaffed wires. I found NONE! I even taped the C115 Harness wires just in case. I've run out of ideas guys, could you help me on anything?

just some things I thought you might want to know which may help solve the problem...

The only thing(s) I have done to the car is change the HU, but even after I changed it, no CEL or anything..this was 1 week ago. (it was a custom HU, but I switched it out to a better one).

2 days ago: Right BEFORE the CEL came on, I was driving around testing the power of v-tec and gunned it a bit. I was really thinking there had to be burnt wires somewhere (heat dissipating off the car, from me revving and gunning it), but I could not find anything. I've gone through 5-6 7.5 fuses trying to figure out the problem. Any suggestions/thoughts? It would be highly appreciated.


its a '96 honda civic ex 150k miles in case you were wondering

Thanks!

 

Check for an exposed power wire for one of the O2 sensor heater elements.

 

+1 i had the same problem in my rsx and it happen to be the power wire arcing off the chassis from my downstream o2 sensor.

 

what did u discover?
