my check engine light went on about 3 weeks ago and never had time to check the codes my ecu was throwin. the other day i went to start my car and the battery was compltelty dead. i had a freind jump it and ever since then the car starts up fine. the weird thing is that my check engine ligfht is now off? anyone know wut might of caused this or if i should be aware of it not starting again?

 

the reason the cel is gone is because the battery died...nothing to keep the memory.

 

oh that makes sense thanks alot for your help
