code 43 o2 sensor
 

I replaced my o2 sensor, plugs, and wires and still throwing 02 sensor code. I have headers, strait pipe to muffler not cat.

lol i also have a set up like this but mines fine

Re: code 43 o2 sensor
 

its not the o2, use the spark plug defouler trick, search, ull find it

Re: code 43 o2 sensor
 

use the resisteors or buy an 02simulator.com

also maybe becuase u have no cat you have the check egine light

Re: code 43 o2 sensor
 

no thats not it b/c i have an Lx and i got megan racing header that took off my CAT and i have just header and exhaust stock mid piping but yeah umm i dont have a check engine light or anything!

~ one thing, if it comes on get an extention to move it further away from airflow... and can somebody correct me if im wrong for emissions testing if you have no CAT but the CEL is NOT on will you pass???
