my exhaust seemed to have burned up one of the wires on my o2 sensor. so am I better off getting a new one or replacing the wire?

and if I do get a new one, will any b18 o2 sensor work, or does it have to be a b18c1?

 

Try replacing the wire first...a lot cheaper than the o2 (especially if there isnt anything wrong with it)

All honda 4wire o2 sensors are the same - even front and rear

 

ok thanks...

Is there any difference between obd1 and obd2 sensors? I'm pretty sure I can find one for cheap, but I need to know which one I am looking for.
