SOURCE: Check Engine light

that code definition is "Evap high purge flow fault". It means you may have a problem with the evaporative system. this system routes fuel fumes back to the fuel tank. If you want to try and clear this code, find the radio code for your car and then disconnect the battery for 30 seconds. Reconnect the battery and the check engine light should be out. You will then need the radio code to reset your car stereo. the check engine light may stay off if the condition was a transient one. If not, the light will come back on after you drive the car two drive cycles. That is: two starts, warm ups and shut downs. If the light returns, have a mechanic check it out.

SOURCE: 2006 kia rio check engine light on and code P0455

A code p0455 most likely means one or more of the following has happened:

  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • Other leak or damaged piece in EVAP system

With a p0455, the most common repair is to:
  • 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

Could be a weak coil on number 4 cyl.
Switch coils between 3 and 4 and see if the code now reads #3 misfire,then you will know you need a coil.
Maybe the check engine light will stay off after the switch.

check the fuel line hose near the fuel regulator for wear as they tend to leak or corrode causing a gas smell inside the car. My 2000 Kia Sportage just had the same problem with the gas smell inside the car.
