just found out my 2002 rsx s has the megan race header on it with no extensions or defoulers on it. after doing some searching it looks like the defoulers are recommended on this set up. you think that because it dont have them it ruined my primary a/f ratio sensor heaters?

if someone has this set up please let me know if i need to replace the sensor or just get the defouler installed. thanks

 

did you check the heater circuit fuse? I'm pretty sure there is a fuse for it

 

sure did. i checked all the fuses and they are good. checked pins a1 and a22 and got 6v but had to stop there. im thinking the rh fried the a/f sensor. i may try to diagnose it farther tomorrow. but even if i find the sensor is shot, should i even bother with the defouler?

 

just put the defouler in. i did it with the CRSX header and no CEL. you dont need the extensions.
