I got another CEL :( - Toyota Yaris Forums

PHXDEMON · 11-09-2009, 08:51 PM

Installed the nitto midpipe about 4 months ago and got a CEL. Installed the o2 anti fouler and it got rid of it for about 3 months. Acouple days ago it turned back on

Anyone else with the Nitto MP have this problem?

get a o2 simulator. if you can't find one i can find you one on the camaro forums.

fill the hole, with a plug, use antiseize. and dont worry about the after cat sensor any more. now if you're talking for the pre-cat sensor...i dont know what to tell you other than to try a new sensor.

I have the Nitto Mid Pipe with the O2 Anti-Fouler, No CEL for me. I had a problem with the O2 sensor bung, but it was a simple re-weld job. I've had my mid pipe on since June. Do you know what code it's throwing?

+1 you probably didn't tighten your gas cap all the way, happened to me

That will throw a CEL

I think I may hear a slight exhaust leak. Is it possible for that to throw a code

I didn't use any washers in between the fittings because there weren't any from the factory. Are you guys using crush washers on your fittings?

Oh man I feel like such a dumbass

I just popped the door and the cap somehow wasn't even screwed on. Thank you kind sir for helping me pull my head out of my ass

Have no way of checking it. No scangauge and the local checker guy is a douche that won't let customers use the code reader anymore

Anyway I tightened up the gas cap and it is still on. Do I NEED to clear the code or should it go away after a little while

hatchbackkid82 · 11-12-2009, 09:46 AM

It even says it on the gas cap. I think the light should go off if you've re-tightened the gas cap and drive around a little bit. That's what happened to my friends IS250 and the light shut off. If not have someone check the code before you get reset just to make sure
