unhook the battery for about 15 minutes... that will reset it ... if the stereo is an anti theft type... make sure you know the code and how to enter it.

Code p0440


P0440 is a EVAP leak detected, try changing the gas cap and reseting the ECM to clear the service engine light. If you can not clear the code it takes about three start up with out any issues to clear the code and after 100 start up's the codes will clear from the ECM's history. Note use the GM OEM gas cap for a replacement, anything else is just garbage and you'll be replacing it again with in 6 months. If it's not the gas cap, need to take it to a garage and have them do a smoke test to locate the leak in the system. Good luck and hope this helps, keep me posted. be glad to help
