Traction control light came on and also read reduce reduce engine power

Hi,

The light coming on usually is the result of a wheel speed sensor but can be something different. Now, if the computer thinks the tires are slipping, it will a power loss to help prevent the slipping. Hence, the rough running.

Now, the best and easiest thing to do is check for diagnostic trouble codes using a scanner. I realize most people don't own one, but often times a parts store will do it for free. I don't know if the vehicle is safe to drive and have it done.

If you want to check the wheel speed sensors to see if any are bad, here are links to help do it:

You will need a multi meter to do the check. Here is a link to help with that:

Let me know if I can help. Also, if you do have it scanned, let me know the code that is found. It will help me point you in the right direction.

Take care,
Joe
