I was driving to Advance auto parts tonight to pick some stuff for my truck. All of a sudden, I noticed the little sprocket light in the corner of the dash even though the car drive normal. While there, I had them look up the code for me and the only code that came up was p1709. I looked up in the manual to see what little sprocket stands for and it had something to do with SMG. I restarted the car twice and drove it to two different places after Advance and the sprocket light never came back up. Anything to be worry about? Thanks
