So I was on my way home from work when the CEL popped up. Got home and used my Access Port tuner to read the code. It was a P2253 and it had no description.

The next day I started her up and within a few seconds the idle sounded odd. Kinda sputtery. I used the AP tuner and found that 2 other codes popped up along with the P2253. It was a P0134 - heated o2 sensor circuit no activity detected (sensor 1) and a P0132 - heated o2 sensor circuit high voltage (sensor 1).

I took a video of the car starting, the sputtering starts at about the 20 second mark.
So far this has only happened when the engine is cold. When the car is warmed up the sputtering goes away. My car usually sputters when at cold idle but never this bad...

Let me know what you guys think it may be.


I know there is a thread about a P2253 but I did not want to thread jack, seems like he is having a different issue.

 

No one?

Well I ended up getting under the car and removing the o2 censor. Checked to see it there was anything odd and re installed it. So far its been ok, no heavy sputtering on cold start and no CEL.

I guess it could just be a loose cable. When the Ultimate racing exhaust was put in the cable protection needed to be peeled back and the 3 wires exposed and routed over the exhaust.

Any feedback would be appreciated.

 

What part of the exhaust did you need to feed the wires over? I'm getting the high flow cat and midpipe soon, just want to know what I'm getting into. Also, how is the sound with the resonator? I'm trying to decide between the mini-muffler and the resonator. Where on LI you at?

 

The exhaust was actually installed by no limit motorsports and they routed the cable over the exhaust and around a hanger so it doesn't touch the exhaust. With the resonator it sounds sooo sexy. Its perfect blend of growly and loud. I get so many compliments on it. I live in Port Jefferson Station on LI. Where u at?

 

Did you ever figured out what was the problem ????

 

i ve been getting the p2253 code it comes and goes all the time i was assuming that thats because im running a catless testpipe but i guess not

 

I being running cat less for a while already and never had that code pop at all.

 

With your AP are you able to clear codes yourself? If you get a CEL from a Catless test pipe, can you just remove cel permantely by using the AP?

 

if you find a solution on how to get rid of the p2253 code let me know
