My check engine light stays on and I got a code of P0340 .what do I look for?

Thank you sir I need all the help I can get.I have had this car 3.5 years and 65,000 miles. I would love to drive this car since I have retired. I have put several remote starters in my other cars but this one gave me the most trouble. Please point out anything anyone can thank of so i can appreciate this pretty blue Corvette. HELP ME PLEASE!!!!!

well, the first thing to do is test ALL the fuses with a test light.you can buy a cheap one for less than $10.00 and check all the fuses in less than 5 minutes! this is a must when a hot wire has shorted to ground!

Thank you Sir I cleared the code and it came back. I even cleared it a second time and it did come back again. Do I need to check the fuses under the hood or in the drivers floor board? I called a Chevrolet shop and they told me that I needed to have it towed over to their shop. The serviceman told me it would probably start at $600.00 and or whatever it would take to get it back right. But that was just a guess and he would need it at his shop to evaluate the problem. How would I check or test those black box fuses in the fuse block area? Thank You
