I have searched the forum and with no luck found any info, I have a catless ZZP downpipe and got the code after racing an SRT4 and NLS thru 1-4 gears. I am about to put the stock DP back on and see if that solves the problem, because I have read that it could be the sensor and I am going to see if it comes back on with the stock DP.

EDIT: I have cleared the code already and about to put the stock dp back on, and see if it comes back.

Thanks for the help.

 

Bump

 

never had a such thing happen to me when I installed my ZZP Catless DP with GMS1 since July. You may have something else going on. what are you list of mods? here is a link that may be the issue with your o2 sensor. http://www.obd-codes.com/p0140

 

My only mods are the downpipe.

 

Looks like you didn't plug in the rear O2 sensor, or damaged the wires. You know you have to twist it before putting it in so that it's not all twisted up after you screw it in, right?

edit: The codes for our car is posted right at the top of this forum under a sticky. Why link off site?

 

otherwise air and moisture will enter in your o2 and possibly damage it. lets hope your didn't twist up the wires during the install. I made sure the first thing I did during the install was locate the o2 sensor is plug at and unplug it before I turned some bolts. so you may have to get your hands dirty again and take it to the dealer with the stock DP, unless you want to pay the extra money to replace your o2 sensor.

 

Thank you for this info, I did not know I had to twist the wires. Stupid on my part, but I did plug the sensor on when I installed the dp.

 

Well looks like I damaged the sensor then I will be putting the stock dp back on and heading to the dealer.

 

Stock dp is on now

 

sehr gut! now take her to the dealer and get a new o2 on.

 

I have to wait to get the cel again

 

You realize they're gonna see the marks on the O2 sensor from removing it...no offense but it's because of you guys doing this and not owning up to it that makes new cars cost more.

 

Yep, you need to do 2 things:

1) stop working on the car yourself. Get help.
2) buy a new rear O2 sensor. See tip #1

 

Yes I know this but i am gonna get some of the carbon from the catless dp and rub it on the O2 sensor and the bolts so they cant really see them....But thanks for your input have a nice day.

This time i did have help and plugged the sensor in right, I didnt know that before.
And now if the light dosent come on and the dealer dosent do it im gonna buy the O2 sensor and install it.
