troubleshooting codes how long till they erase
 

\do trouble shooting codes erase by themselves or do I have to do something I aalready fix the problems that it had according to those codes

You need to have the codes removed if you don't have the means to do so.

some codes are "soft codes" and others are "hard codes". soft codes go away after so many key cycles. hard codes can only be removed with a scan tool.

The codes will be removed after a certain amount of drive cycles If the issue was resolved.
