regen problems

[Big Al]

2009 isx has been having regen problems. the truck came up with the flashing regen light and the solid check engine light about a week ago. it needed a forced regen so when i tried doing that it wouldnt go. i ended up running both sections of the stack down to cummings to have both baked. everything is back together and the light still wont turn off. it comes up with a severe regen code and also an incorrect voltage reading code at 1 of the exhaust temp sensors. ive looked at the sensors and replaced them all due to old crummy looking sensors, ive checked the wiring, and all the connections. everything looks good. has anyone else had this problem? :bangh
