1 I cant get my check engine light to stay off
on my 2006 honda civic 1.8l ex my check engine light will not stay off. comes back on in 1 second. codes read p0498 & p0135...i installed a brand new 02 sensor. haven't gotten to the vent valve as of yet because my light keeps coming right back on. checked all fuses (good). i even checked the wiring going to the 02 sensor with my meter. not getting the full 12v but i get somewhere around 2v-1.8v. i thought that was strange but i don't know it could be normal. is there anyone out there who could please help me or give me a little insight !!!

Yes this is a common issue for the (8th generation) 1.8L civic years 2006-2010. The Catalytic converter is dirty/clogged causing the O2 sensor to throw the code. The black market High flow cats are between $120-$200 decent onesdepending on brand etc. About exact replacement as you can get, for this type of replacement which is comes off the front of the engine manifold ( under the hood).
