I have a code of PO456 Hyundai 2007 Accent


This tends to be a Fuel cap seal, when getting fuel be sure to tighten the gas cap at least three clicks. Any parts store should be able to reset the service engine light, if the light persists, remove your negative battery cable for 30 seconds with the ignition turned to the run position. replace negative battery cable and and the code should be gone. This resets your cars computer. Be aware that this also rests the Drive Learn program, and the car will take 10-15 miles to reset this, it may run a bit rough during those 10-15 miles but should clear up afterwards.

How do I clear the error codes on a 2001 Dodge Ram 3500 diesel?


You will need a hand-held obd2 scanner to clear the codes. Advanced Auto store will do it for free if you have one in your area. Other part stores will also do it for free.
You can disconnect the negative battery cable for 10 minutes and replace it, but it doesn't always work. Sometimes the codes are stored in memory and require the hand-held obd2 to clear them
