i have a 2006 2lt that having the same problems as others with the traction control light and check engine light. I took the car to auto zone to have the codes read but the scanner whould not pick anything up on my car. The Guy told my the connection was dead at the plug and there was no power to the scanner. i was thinking that it could be the intake silonode like other people was replacing. would it be better to replace it or take the car to the dealer to see it if they could get the cades scan.

 

try a different auto parts first..

 

The scanner not being able to pull codes could be fixed by this Special Policy.
