Engine Light came on today

[vettelover510]

I have a 2003 Corvette, replaced the stereo Saturday. Didn't drive it all weekend, now the engine light is on. I checked for codes and have so many, can't get them all wrote down. Any ideas where I should start?

When you entered the diagnostic mode to view your codes, they were scrolling by kinda fast because you were viewing them in automatic mode. You can also view them in manual mode, which will allow you the time to view them one at a time and write them down. See

for a more detailed explanation.

Try clearing them all and see what comes back.

Don't know how to clear them, but I did come up with the codes. The only one that concerns me is code P1416 which is the Secondary Air Injection Bank 2. It has an H and a C by it, which means there is a history and a current. Been worrying about his becoming a money pit. I hope I'm wrong.

Reset all my codes. Engine light is now off. I will have to see if it throws up another code on it. Thanks for your help.

You didn't write them down first???

I did write them down, but there are alot to post. Majority had to do with disconnecting the battery to install the stereo. Others were mirror or seat adjust issues. There were 25 in all. The main one I'm concerned about is the one listed above. 10-PCM P1416 H C

Sometimes, a code will be thrown in association with another one. The more information you provide, the easier it is for people to help you. But hey, it's your call.

Okay, P1416 is sometime thrown in conjunction with DTC P1415. That's why you always post all your codes. Here's a detailed explanation of the DTC P1416.
