ok guys i installed my race header today and the greddy evo 2 exhaust and i put the o2 sensores on and everything and the check engine light still went on any ideas on how to take it off?? Help please thanks

 

Did you disconnect the battery when you installed it? I'm pretty sure that would have helped, you should do that with every mod. But otherwise get it scanned and see what it says.

 

yeah i did disconnect the battery! where can i take it to get it scanned??

 

Dealership would be able to. Auto Zone normally would but it's too new so they won't even be able to scan it. Depends on if you want the dealership to know about the mods..Check the sensors again to make sure they are good.

 

ok i'll check the sensor. should i unpluge the battery again when i check the sensor?? what would the dealership say about the mods??

 

Yeah I would check unplug the battery. Well if there is a problem directly related to your modification, they can say it's not covered with the warranty (unless they're cool). And I'm sure they will make a note of it that you brought it in because the CEL came on when you installed this, making it directly related.

 

ok thanks a bunch for your help bro i appreciate it so much!!

 

take it to auto zone they will scan it. had mine done. you need to get the defouler mod and put the cat o2 sensor into it then out that into the header. your gonna throw a CEL unless you have one. the batrtary isnt going to do nething until you get the defouler mod.

 

yeah no cats=cel

Defouler Mod is simple. I am sure op will ask this question next.

Go to your local pep boys or autozone and pick up part #42009. It is a spark plug defouler. Your going to go ahead and drill the entire little hole out one of the plugs so that you can slide your o2 sensor into it. Then screw that unit into the other one and put it back on your header.

Disconnect the battery for about 2 minutes or so then put it back on. No more check engine light.

lol yeah but if he knew about that he wouldnt be posting about his cel no would he

 

well i said hey get the defouler mod. im sure hes got some brains to look up what a defouler mod is. now instead of drilling out this hole b/s just order one off ebay. the way i got mine. cost about 15bucks get it next day. works like a champ. o0o yea and its a one peice.

 

Yea most likely its because he dont have the defouler on his RH now.

To the OP just get this done and you "shouldnot" get anymore CELs. But don't be surprised if it came back once in a while though. :D
