What is code P0455- Emissions leak
well you can have o'reillys use the scan tool to clear codes in the computer and the light will go out unless the problem still exists then it will come back on. this code means that maybe something is wrong in the evap system. i have a question for youl. when you get gas do you stop when filling up and the pump kicks off the first time or do you kepp filling a little more each time trying to top it off better. what many people do not know is that you can do this but it is filling the lines of the evap system with gasoline which will eventually cause problems with the system. the evap controls fuel vapors from the gas tank and it can not work if it is full of gas. i am sure you understand gasoline turns to vapor quickly. gas in your gas tank does too. to keep it under control the evap system gathers it and purges it with switches and sensors that can be damaged by liquid gas. so can vacuum lines. they will swell and leak and all of these will cause the system to fail and the computer will set a code and the light comes on. also the gas cap being lose while the engine is running will do the same.if that is the problem you will need a skilled tech to figure out what is wrong and replace it. if your getting gas always stop the first time the pump kicks off. hope this helps and good luck
