So the o2 sensor in my 95 integra was replaced today. The end of it looks like it was white hot and burnt all to hell indicating it may be running hot. Any clues what's causing this or has anyone seen it before? Car was throwing a 41 CEL but that's gone away since replacement.

 

im not sure man every one i have ever taken out have been from high milage car so far and have all been white i have only gotten one black one so far and it was more of a dark grey
