i dont know nothin bout cars, help me. heres the story, i just got my budget y-pipe installed. after the shop installed it no check engine light came on. now im home and wen i went to start it, check engine light is on. ive never seen that light before, ever! what is it? how do i make it go away?

 

It's your Oxygen Sensor(s). Reset the ECU and see if it comes on again.

 

I would also check to make sure they didn't damage the O2 sensor connections when installing the Ypipe.

 

ok, i dont know much bout cars, how do u reset ecu?

 

if it is that i have to reset the ecu, wouldnt the light have come on wen i first started the car after install or does it usually take a while to come on?

 

1. Read the stickies before you get banned
2.
3. Welcome to the ORG and stop modding your car before you read the stickies.
4. One more for not reading the stickies

Takes a little while. I believe all you have to do is turn the screw on the ECU to reset it. Let me get a link for you...

That will tell you everything...

 

thanks njmodi! 1. ive read all of them, just dont remember! 2.not everyone is blessed to know the mechanics of cars, u know more than me at cars, good for u, im better than u at other things! 3. three months too late, once again ive read them, but care not to search them again! 4. one more for not asking ur opinion or ur information! and 5. if it sucks dont read it buddy!!! thanks again tho, a simple read the stickies or heres the link would have done just fine!

 

Your Welcome

 

The point of the stickies is not for everyone to memorize them. The point is to look there first when you have a problem. The CEL is the MOST COMMON problem and there are 2 stickies dedicated to helping you out with diagnosing the CEL.

I'm actually horrible with cars. I just read a lot. I just know where the info. is and share that when I can.

If you don't want to put in the time to find the answer to YOUR OWN car problems, why should others spend their time searching for you? Not sure how that works.

If you can't take some humor, sorry about that. Welcome to the ORG, as I said earlier. Enjoy your stay.

 

no problem, nice to meet u bro! i read that stickie and imma go reset my ecu now, thanks! ill come to u if i have the problem still, after i read the stickies first of course!

 

No need for sarcasm. Just go pull the codes and get back to us - we're not asking for a lot you know

 

oh, im a very humorous guy let me tell u, thats y i decided to show u some humor bak.

 

<--- thats me.

Man Nmex is on a rampage today!

 

Hehe yeah, you beat me to this one though ... Props on helping this guy, your posts are the only ones that are valid in this whole thread ... And black max

 

Wrong. Black Maxima lent a helping hand.

 

<--- That's me...


HAHAHA HAHAHA

 

0303 and 0304, front left heated o2 sensor, and....knock sensor. i reset it. is it possible that these are faulty and just popped up because ive never had my freakin cel come on ever, until i got this y-pipe that is.

 

Helping hand = Valid post, but in an invalid/pointless thread.

 

The KS was tripped by the O2 sensor. The O2 sensor might have been damaged/contaminated when the Y-pipe was installed. Reset the ECU, see if they come back. Start with replacing the O2 (if the code comes back). The KS is often just triggered by it.

 

ok, that sounds like good news, i think? so, if the cel doesnt come bak, im good? or no? thanks in advance njmodi, very helpful!

 

HAHAHA

See, it just took him a little while to warm up. He's up to making good posts now...

 

I would assume that the problem has something to do with one of the o2 sensors not being hooked up properly after the install. Just my $.02

 

oh, btw, wen i read the 100,000 forums on y-pipe, i figured it would give more sound because of wut everyone says, but that thing is louuudddddddddddd. i sound like a freakin race car now!!

 

Not if you have stock exhaust besides the y-pipe,

 

Well sort of. If the CEL doesn't repost, just check for codes anyway - since the KS (if its bad) doesn't set the CEL, but the 0304 will be stored (a little wierd, but thats how it works). If the O2 sensor is bad, it will repost and code and trip the CEL. Again, if both codes appear at the same time, just fix the O2 sensor issue (replace sensor) first. Reset the ECU and check a few days later to see if the KS posts on its own. Only then do you want to replace the KS.

 

i guess, but i dont have that, doesnt most people have aftermarket exhaust wen they get y-pipe. for the most part atleast. well, takes some gettin used to, just like wen i first got the exhaust.

 

I'm done with my "be mean to newbies" phase of the day.

 

will do, njmodi!
