I have a 2008 Aveo5 LS Hatchback AT trans. My Problem is a weird one my engine light does not work properly. When i first start it up early in the morning to go to work the engine light comes on then shuts off after the self check like normal, but then never comes on anytime after that in any key position. I took apart the dash to see if maybe the connection was bad, but when i took it apart to look at it everything looked fine i also checked the bulb while i had it opened and it appeared to be fine as well and i figured that cause it does work sometimes. i checked all the fuses in the cab and under the hood and they are all fine. Could it be the ECU is bad and not sending the information to light? In AZ this is a must in order to pass emissions so any help would be greatly appreciated.
