1996 lexus es300 check engine codes?? o2 sensor? reset light?

trying to get my car back together. i got a code of P0135 ( bank 1 sensor 1) for the o2 sensor heater but i don't know if it is upstream or downstream. also a code came of P0401 for egr flow insufficient? i'm lost with that one. also if anyone knows how i can at least reset my check engine light. i've tried pulling a cable off the battery but it came back on after 20 minutes. any help would be greatly appreciated. thanks.
