longtube headers and check engine light

after installing dtlong tube headers, urd y pipe and 02 simulator my check engine light and traction control lightcame on i just put them on and im beat so i really didnt do much troubleshooting yet. i was just wondering if anyone had the same problem with the same set up? i was thinking its because the simulator was set up for a stock truck with the only mod being the headers and my intake might be trowing it off. or it might be a simple leak or weak conection with the sim and the ecu. any advise would be helpfull especially if you have the same headers as me

 

I think with the new headers you need an 02 sim I think urd sells them

 

Yeah, just check over your wires again man. If they all look good and it still isn't working, go back over it and check to see if you connected the correct wires.

Hello, welcome to TW!

 

To check an o2 sensor, you stick a multimeter on it when warmed up and check the voltage, I believe it should be between .4 (lean), and .9 (rich). I might have that mixed up but I don't feel like looking it up. Anyways, try checking your o2 simulator with a voltmeter and it should be in that range.

 

Definitely check your 02 sensors.

I had my 02 sims wired up and headers on etc and I didnt have the lower 02 sensor plugged in far enough to get a solid connection so I had a CEL.

Check it all again since it will throw a CEL if everything isnt nice and tight.

 

i got it fixed. one of the wires was loose so i re soldered it and its running great now
