It's been now over a month I think that I installed my DP and deleted the cat. The SES light hasn't come up because of that. I think I read that it took a few days for it to come up but it hasn't and I drive the car every day, atleast a couple hundred kilometers each week.
The only way to set that code to "not report" is with a PCM programming thing and not just with a code scanner right?
Any ideas on that?
Thanks.

Right...you have to set it to NR via a tuner.
Sometimes people haven't gotten an SES from it...its kinda just dumb luck sometimes.

ok I see thanks LoL...

Has you SES light come on before? Might wanna check it because we just found out there was no bulb for the SES light in my old GT when we bought it...

Yeah it used to come up a lot back when the CPS was faulty and the spark plug wires were like bubble gum. It also comes up before i turn on the engine.

Do you have the sensors plugged in?
05-12-2010
if they're not plugged in shouldn't they come up? maybe his car didn't get the correct driving pattern for diagnostics? maybe i'm crazy?
05-12-2010
Yes, they should come up. But I've seen where folks keep them plugged in and zip-tied to something underneath the car.

If you deleted your rear O2 it will eventually come up just a matter of time, but if you left the O2 welded into the pipe back there you should be fine.

It could throw a cat efficiency lower than expected light, or some such. But at this point, who knows?Originally Posted by Ibwrong

if it was gonna throw a code, im pretty sure would have by now... my p0420 comes back within 2 days after i clear code.

Yea check that out too, not that hard to take apart. The bulbs are small and expensive lol $5 for only two of em and they're no bigger then a penny lol

Good point didnt think about that..It could throw a cat efficiency lower than expected light, or some such. But at this point, who knows?

The O2 sensor is in place, only the CAT is gone. SES bulb is fine, it also turned on not long ago when I left the fuel cap opened. i'll double check later. If it's not throwing a code because the CAT is gone I'm fine with it. that light being on all the time bothers me a lot lol. I was just wondering why it didn't threw a code. My next mod will be a PCM anyway. Thanks for the replies.
05-12-2010
Okay, so you left the secondary o2 sensor in place. Is it in the pipe or just hanging out?
05-12-2010
it's in the pipe.
05-12-2010
Gotcha. Well, it's good that you don't have the light. Just know that it might come on at some point.
05-12-2010
cool thanks. I hope i have the other PCM by then =D

Let them know to kill that code before they send it to you.
