SOURCE: my check engine light came on 2003 dodge dakota

This code is normally caused by a loose gas cap or a bad EGR valve. It is the code for the evap system on your truck. You can go to autozone and they will clear the code for you if you can not do it yourself. You may need to replace the gas cap and or the EGR valve if the code comes back up, these are normally one time things due to the cap not being fully tightened.

I have the P0456 on my dodge caravan sxt 2007 with the keys.

This is usually caused by a gas cap that was not put on properly after a fill up. If this is the case then simply tighten the gas cap and the check engine light should go out in a few days with regular driving or reset with a code reader. You may have to replace the gas cap if the code remains. be sure to get the correct cap.

Check the link above for further tests.

Is the gas cap on tight or is the seal damaged? If it needs replacement, get it from the dealer.
