well i recently had my LTs installed and a catless y-pipe, well i bought 2 o2 sims from summitracing and i plugged them in today and im still getting the SES code, so i took the truck to autozone and had them scan it, is says its throwing four o2 codes, what the hell happened here?????

 

on the sims is there a lil led light if there is it should be blinking if they are working, i know this is how mine are.

 

were the codes thrown before you added the sims? if so, give it some time and the light should go away.

 

Ya there is a lil led light, haven't checked to see if it was blinking or not, about how long should it take to kick on blk03???

 

ive had them on since friday afternoon and the SES light is still on

 

anybody else?????

 

Did they scan and clear the codes?

 

I'm not sure, he just hooked up the little thing and said "its your oxygen sensors"

 

Anybody else??

 

it has to be cleared, and if you did get bad o2 sims then it will throw the code again.

if you dont clear the code the light will stay on regardless of wether it is a good or bad o2 sim.
