sorry for my little english,Two days ago i connect the test pipe, ultimate racing and catback greddy, and now I get the P0140 code, which will be the code?

 

P0140 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 2).... the pcm is not seeing the signal that the sensor is generating or something similar.

whats your question??

 

My question is whether the sensor is dead or what happens?,I have to replace the sensor?

 

you are running a test pipe that is what is making you throw the code. If you want to get rid of it get a 02 simulator or put your cat back on

 

[QUOTE=Draven83;6728376]you are running a test pipe that is what is making you throw the code.
yes, but the ultimate racing test pipe,is ready to pledge that no code

 

to be or not to be
that is the question

 

in spanish, monte el test pipe UR y despues de 2 dias me prendio el cel code P0140 ,se supone que con el test pipe no prenda, o no se si es que el sensor esta dañado ??

 

So your test pipe is throwing a check engine light, and you want to know why, since the UR test pipe is supposed to come with a CEL fix, right? You should PM someone at Ultimate Racing to find out why you're getting the CEL.

 

yes , and the p0140 code ,is a sensor dead or by tespipe

If you are having issues with a product, contact the manufacturer (ultimate racing in this case) first. They usually will have some things for you to check, or keep you from doing un-necessary checks in case you dont have something.
