I have an 05, 06 and a 2007 cobalts and the check engine light is on all of them. They are all running fine. I took them to auto zone and also a local mechanic and their testing equipment would not read the codes or even power up. I called my local GM dealer and they told me those testers won't work and I would have to take it to them to code for $88.00 each. Is this true? Is there other testers that will work? Thank You, J.
