I was wonder why my traction control and emergency brake in yellow light on? I just got done replacing my idler pulley, put everything back on and started the car to drive and now these lights are on. I did not disconnect anything exept for my MAF, and the the plug on the radiator shroud. WHat could this be?

Surprisingly (or maybe not but it doesn't make sense to me), a fault in your intake readings can cause this. Make sure all the contacts on the MAF plug are clean and there's no damage and that all the intake connections are tight. Then get your codes reset.

I had the same codes/lights/limp mode from a leaky intake pipe and just tightened everything up and it was fine.

There is something wrong with your traction control system, who knows what caused it though

Well I tightened everything up, so we will see, I hve not had the chance to drive it to see if it will clear. I started it up and the lights gave not gone off yet. Also I notice that is turns on with the car, opposed to comming on when the car starts moving like I have seen.

Thanks everyone for helping me out and throwing Ideas out there.

Sorry Cystal ball is broek and I lost my magic turban.... Get the codes read in the ABS DSC only way you will know whats wrong. A maf can set a DSC codes as the DSC needs to see a load input over can from the DME to calculate slip rate and traction control. Primary load signal comes from the Maf.

well i found my problem. My lights came on after i replaced my fan blade. Well looking around the other day i relized that the fan shroud was on 100% bolted down. I put a plastic clip where i metal screw should have gone, on the passenger side at the top of my fan shroud. I put this bolt back on, just take it right now even thinking it had anythign to do with the DSC, and when i drove my car after that the lights went off......i dunno, why that screw mattered, but i dont care cause the lights are off not
