is your car throwing codes at you ? or does it just run crappy?

 

What if my check engine light is not on, should I still check if I have any codes?

 

Yes, not all problems will cause the light to go on.

 

What will the light do if there is no code?

 

When there are no problems, the light will not come on. When you run diagnostics, you will get a code of 0505. This is the "all clear" code...

 

My car is running fine but should I just check it anyway to be sure? I've had lots of problems the other month.
