Hey, I have a 98 civic hx manual, and its giving code p1166. does anyone know exactly what the problem is?

 

primary O2 sensor

 

Hey thanks a lot...thats what i thought it was, but didnt want to go ahead and replace it before being sure. Do you know where I can get one at a decent price? everywhere seems to have them for $300-400. Is it impossible to use one of the 4-wire universal types with this 5 wire system on the hx/manual?
