Oxygen censor


Asked by Oct 15, 2016 at 08:38 PM

Question type: Maintenance & Repair

I have a 2012 Honda Civic that's randomly
showing a check engine light with a "check
emissions system" message it's come on
and gone off again 3 times now. I've had
the engine code read and it shows a bad
oxygen censor. Is this a part that can
gradually go out or maybe just have a bad
connection. I would prefer not to replace
the part if it is not necessary.  I would like
to go the work myself as I feel a shop
would charge too much for possibly
unnecessary work.
