i know this thread is old, but i recently replaced the clutch in my 95 civic hatch and one of the wires for the coolant temp sensor broke but i dident know it at the time. i drove around a little bit and my air/fuel gauge said rich and my check engine light came on. i fixed the coolant thing, but now i have a code 41 for the oxygen sensor.

sometimes the light is on, and sometimes its off, the sensor is fairly new. is there a way to clean it?( i think it got dirty from running super rich for about 20 miles). i might try reving it up pretty high and resetting the ecu.

update: i ran it around at high rpms today and reset the ecu and it seems to be fine now. i dont know that i really fixed the problem since it comes and goes, but im happy for now.
