Your check engine light continues to come on because there is a problem that your ECU has detected. Yes, you can erase the code by removing the battery cable or by removing the EFI fuse under the hood. You will have to get the trouble code pulled to find out what is wrong.

Good Luck

Check your air filter. My K&N gave me a check engine light all the way up to the Texas border. Was letting in to much air.
