Check engine light question on a 2006 Mustang GT
I searched the forums and found a few threads pertaining to the check engine light, but none that addressed the issue I ran into tonight. So here is what happened, I'm going to provide as much information as possible:
I was driving home from work tonight and I hit a small pothole going about 15 mph (while turning before merging onto a road), it made a thud sound, but no portion of the car or or rim or anything hit or scraped the asphalt. And only one tire went over the pothole. A few miles later I noticed that my CEL was on (while going about 60 mph), and this was the only thing that I could think would contribute. I'm almost positive that I would have noticed this light right after I started my car and proceeded to drive home, so I'm fairly certain it happened right after I hit this pothole.
When I got home I turned off my car and restarted it and the light was still there, I did this a couple more times and the light stayed on (no flashing). I read where disconnecting the neg. battery terminal and letting it rest for 5-15 minutes, and starting the car back up might solve the problem by resetting the computer. If I do this, and the light does not come back on, is it safe to assume that there is no problem? and it was just a fluke reaction? Or should I still take it by the dealership and get them to check it out? I'm assuming that if the light stays on after I disconnect the terminal, I will have to take to the dealer.
I have a 2006 GT w/ 11k miles that is still under warranty. The car is completely stock with exception to the stripes and louvers. If I have to drive it by the dealership to get them to look at it, there won't be a diagnostic charge will there? I would certainly hope not.
So does anyone have any thoughts, ideas or suggestions for me? Any input would be greatly appreciated. Thanks in advance!
