Well, battery light comes on sometimes when I start it, as I drive it maybe ten blocks it goes out. I was going to have the car inspected but my cousin put it on his thing and got the code p0330. What can I do? What could be causing it? Please help if you can I need my car inspected.

I do not know about the code but my car did the same thing and I thought it was the battery that was bad. However I found out my alternator was not charging. So I had to replace the alternator. The mechanic said the car was running on the battery only and I should not keep driving the car because it could leave me stranded. My car is a 1992 Chevrolet Corsica. It is easy to check the alternator at any car parts stores for free. Good luck!

Great addition to this thread! Please feel free to help out whenever you are on the site :)

Here is guide to help you test the alternator. The code is for the knock sensor which will trigger if the engine is overheating. Just clear the codes once the engine overheating is fixed.

When you checked the voltage was the battery light on? Also, the p0330 code could be from the knock sensor going bad or internal engine noise. Does the engine make noise when it is running?
