2005 honda civic bank one sensor one not communicating.?
engine light is always on. 136000 miles. changed out the top o2 sensor and it didn't fix it. have unplugged the battery for a day. didn't work. reset it 3 times worked for 3 miles and service light back on. this is what the code read i believe. can i unhook it at the computer or something to check the plug? anyone know which exact plug it would be? suggestions?
