I got a 97 Honda Civic HX (wish i didn't) with 155,000 mls and this car has cost me a lot of money on repairs because its a special model ive had to get a new transmission, clutch, 2 new c.b. joints, and the list goes on....
But anyways my check engine light has come on so i took it into autozone to diagnose the problem and the code was related with the o2 sensor and the guy at autozone looked up a replacement sensor and couldn't believe what he saw and that was the price for my type of model its was like $400 for a new sensor so when i went home i took off the manifold cover and noticed a good sized crack starting pinpoint sized at the o2 sensor threads and then progressing a little bigger towards the back side and stopping so i got thinking that maybe the crack is what is making the o2 sensor set off and not the sensor itself, ive tried silver solder and it cracked and then jb weld just the other day and same thing and i figured its from the high temperature that the manifold creats that made both materials crack so my question is should i get a new manifold and see if that fixes the light or should i get the sensor and see if thats it? Im stuck in a bind between what i should spend money on to try and fix the problem...

 

Got an HX too man...yeah, I've heard that the HX uses a special "wideband" o2 sensor, and yes, I'm pretty sure that is an accurate price. Though I think I've seen them online for around $250, though I would definitely make sure that those are the right ones, b/c companies sometimes dont know that the HX is different.

As for your fix, man I can't remember but that MIGHT be covered under Honda's emissions warranty...its 14 years or I think?? 150,000 miles. You say you have 155K, but if you documented it beforehand or find a cool dealer they might fix it for you since its so close to 150000...they get paid either way. I've had a problem w/ my EGR on my 96 forever, unfortunately I'm about 100K over the warranty.

good luck

 

hey I have the same car and one time I had that code but it was because of the air/fuel ratio kind of but I never changed the O2 sensor and enver had that problem again

 

Hey thanks for the replies...im going to go ahead and weld that crack with wire feed and then ill try rod and ill see if that turns the light off but is there any other way to reset your check engine light without disconnecting the battery terminals, i got a cd deck that i dont want to have to set all the shit again.

 

most definatley welding it is the way to go hx's are weird mine did the same damn thing but I took mine to a pro welder(or so he says)and he wire welded it and now its fine
