| 91 honda civic check engine
Txgreasemonkey, Thanks before on your help with the check engine light and sorry to be so long, but had family issues to deal with. I did check the codes and I have a constant single flash. I assume this may be the oxygen sensor according to my Chilton book. I tried to rest by pulling the battery cable with no luck, I also do not have a 7.5 amp back-up fuse? I read your re-marks about the universal sensors, but my question is do you think this is the right direction and is there a way to test the sensor since ther is plenty of money involved? I'm sure this is the original one with 162,000 miles on it? Thanks for all your help!!
