I have a 98 civic with a built up 95 1.6 sohc vetch with a drag 3 turbo kit. I accidently rewired my o2 sensor wrong. I hooked up the signal wire and the heater wire up backwards. Now i get a check engins light on where i did not before. I hooked them beck up the way the were but no difference. Is it possible that i have screwed up my ecu?? please help

 

jump your ECU to find out what codes it's throwing...

jump your ECU, put your ingnition in "on" position
check engine light should light up and would start to throw a code...during this process, if the check engine light stayed lit, you have a code 0 which means your ECU went kaputz....

hope this helps...
