Generation IV External Engine - ENG SEN fuse blowing

I disconnected MAF and reverse lockout. ENG SEN fuse blows when key is turned on. Any ideas dialing in the fuse problem? TIA!

No exhaust mods.

I am currently experiencing the same issue on my WS6 (I know, its a LS1.) I have cleaned the maf, and even replaced the maf (with a $15 scrapyard special) and that didn't take care of it. Next weekend I'm going to install a catback, and I will take a look at the o2 sensors. I picked up an o2 sensor on Amazon to use as a replacement if it is needed. I am also going to inspect the ground connections underneath. If the issue doesn't lie there I must have a short somewhere in the looms. I also still have the stock exhaust setup.

i had this problem about a month and a half ago. i kept blowing the EGN SEN fuse also. the codes that came up were the maf sensor and all o2 sensors. i replaced the maf with no effect. come to find out that the bank 2 sensor 1 o2 wire harness had melted to the exhaust pipe because it was not routed properly after some one messed with the car in that area. the reason it gave me a maf code still after i replaced the maf is because the maf and the o2s are all on the same circuit. all connected by a pink wire, i really hope this helps yall find out whats wrong or at least leads you in the right direction

Well, its not the o2 sensors either. There must be a short somewhere in the line. Crap.

I faced this problem 1 year back and as i remember the issue was the 02 sensors are making short , replaced them and it's running good .
Check the two 02 sensors maybe something is making short .
