SES light on after 3 weeks with Y-pipe.
I recently swapped my Y-pipe and everything's been fine but now I see a SES light. I'm pretty sure it's a bad oxygen sensor but want to know what everyone's experience has been. Also tonight I'm going to disconnect the battery to try and reset the ECU.

So are you guys saying that if it an O2 sensor issue, its just a matter of replacing it? Or is this a bigger issue? Sorry, I'm ignorant, but would like know more about this for when I get my y-pipe.....

After I installed my Cattman Y-pipe, my SES light also went on. I bought an o2 simulator and plan to install it rather than getting another o2 sensor. I did reset the SES light several times and still comes back on.

just get the code read and then go from there.

your o2 sesnor is not nessicarly bad it's getting high voltage because of you y-pipe even if u set ur ECU it will come back in 2 or 3 days i hears some people say u can get a new o2 sesnor and it might fix it some say it doesnt help at all the light comes back on. but it's defently because of ur y-pipe good luck

I'm going to get the code pulled. But I may end up putting the stock Y-pipe back on.

i put my stock y pipe on my 2k max fed. and the ses light still comes on. i reset it like 3 times. also, the obd2 scanner said that it was high voltage/slow response on bank 1 sensor 2, so im guessing the 2nd o2 sensor on the y-pipe. anyway, i bought another o2 sensor and will be putting it in soon, but is it really the ypipe that is messing it up?

Cant beleive this thread is here. After 3 weeks from my y-pipe install, my SES light comes on and I was wanting to post a thread. Thinkin o2 also, i'm autozoning and bringing to my muffler man. Which o2 needs to be replaced? U GUYS R GREAT!!
#17
And by the way, i dont hear the same swoooosh i used to hear with my warpspeed when i first installed it. I'm noticing puttering on accelleration between 1-3 rpm. Could it be the fitment with the warpspeed? But if u cattman guys also have this, hey. Whats my price for an o2, group deal? I have a 2000, too!
#19
they should print out a receipt on which sensor it is .... ie bank 1 sensor 2 which is the one mine went crazy on..... i not sure exactly where it is... i think its the 2nd sensor on the ypipe, but not sure...
#21
Well I went to Autozone today and the scanner pulled up a misfire code. Before I went there I was sitting in line at the bank and felt the car misfire. This weekend I'm going to check the plugs and see if any are fouled up.

I changed my plugs and I still seel it misfiring every now and then. I think I might have to change out the coils next. The only other thing would be the O2 sensors. I'm going to be removing my y-pipe so I may just change the o2 sensors while I'm there.

My main reason for getting rid of the Y-pipe is the deep growl it puts out. It's just too loud for my taste. I do feel the performance increase, but it's not worth the sound I want to put out. I have to work out of my car for a little while until I can get a truck. And pulling up to a potential customer with a loud car doesn't go off too well on a business point of view.
Didn't say I was getting rid of the Max!
Just need a truck for work.
