I just bought this Pontiac this past Saturday. Later that day I started getting messages on the "DIC" to "Service Engine Soon" however no codes when I try to retrieve them. What could be the issue?
It had 75,766 miles at the time of purchase.
After trying to retrieve the code I started to
get "Electric Charge Failure" however the
alternator is charging at 13-14. Both of
these messages goes away without any
issues that I can find. Could the computer
be giving false errors, if so what would be
the fix? Of course, while it is still under
here is the owners manual. http://www.vadengmpp.com/owners-manual/pontiac/2006-Pontiac-GrandPrix.pdf
It depends if it's on steady or flashing. If it flashes your car needs attention very soon. If on steady it may be something minor. I recently decided I could cut a corner and run regular unleaded gas. Well the car had different ideas, apperently that premium fuel on the inside of the filler door isn't a suggestion. They really mean it. My service light came on and after a bit of looking in the book I found that after a few tanks of the right gas it should go out. Two tanks later and it did. I hope it's something minor. Good luck.
Thank you both for your prompt replies! I believe I have found my issue, the battery terminal was very loose. It literally just sitting on the battery post. I tightened it up and have not had any issues since. Again thank you!
