Ka24e persistent code 32

[nwg916]

I can't seem to find out why I keep getting a cel code 32. I've tried 3 different functioning egr valves, 4-5 functioning bpt valves and many different egr solenoids. I've replaced all vacuum lines, and cleaned out the intake port for the egr. All vacuum lines are hooked up correctly. Ive also replaced the egr temperature sensor with a brand new one from the dealer. I've checked voltages for the egr solenoid, and the ecu both read correctly as the fsm says. I've been trying to figure this problem out for weeks. The other day I hit a speed bump and it busted a whole in my cat but I'm not sure if I fixed the problem and now the hole in the cat is causing the light or what. My timing is also advanced a little, not sure if this affects the egr or not? I'm stumped if anyone has any ideas I would greatly appreciate it! Thanks
