Still reading p0455 evaporate test complete no leaks on hoses

this obd2 trouble code table can help you understand the meaning of code. http://www.chinasinoy.com/service/how-to-understand-trouble-codes-37.html And for this code, you can try this: Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back. Otherwise, replace the gas cap, and/or Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary.
