Hey guys I was going to clean out my IACV and as I was dismounting the air filter and then the throttle body I had issues with the 12mm screw and I have work in about 30 mins so I stopped and put the air filter back on but as i was doing that the VSA light on my car turned on and its on solid.. What should i do?

 

go back under the hood and make sure you have EVERY thing connected

 

Everything looks and seems connected

 

If the "VSA" light came on after your work, chances are something was disconnected or loose.
If ya already re-checked your work, simply reset the CEL.

 

How do you reset the VSA light?

 

^^Unplug the battery for 15+ mins (I think, I know that is how you reset CELs)

 

There are 2 connectors that are "similar" and are easily swapped causing the vsa light to come on. I had gone back over my brothers work on his 02 cls a few years back and that was his problem. OP, take a close look at all connectors

 

Ill check it out I think everythings connected right but if not just disconnect the battery for 15 + minutes ?

 

does any body have a picture that could show what these two connectors are?
