These codes are for the evaporative emission system.The 455 is the vent solenoid.The 455 is a large leak in the evap.system.The vent solenoid I would replace because they go bad and will not work because they are under the vehicle in the rear of the truck.There is a bulletin for these and the vent valve is installed in another spot.The number for the bulletin is 02-06-04-037E.You should also look for a broken or loose hose or pipe that might have came off.Specially if you ran over something.If none found it could just be the vent solenoid stuck in the venting position.Good luck.

SOURCE: Left front wheel clicking. think wheel bearing.

Clicking, especially while turning usually more so points to a problem with the CV joint, or axel, the easiest way to test a wheel baring is to jack up that side of the truck until the tire is off the ground, leave the lug nuts on and try to wobble the tire in all directions, if everything seems solid it is not likely the bearing casuse the sound, another note when a bearing starts to go bad, it usually hums opposed to clicks. Im sorry i dont have a diagram, but this proceedure should get you on the right track in diagnosing the issure, good luck!!

Code p0455 gross leak/ no flow


In general terms, the code means there is a leak in the vent system for the gas tank. The most common cause is the gas cap, but it could also be a leak in the tank, a damaged hose to the vapor canister, or other problem.

2005 chevy 1500 silverado eng. light on ran code p0455 and p0449 how to fix the problem. and how much work it takes. thanks STEVE.


P0449 is the evap vent valve solenoid circuit malfuntion.
P0455 is an evap gross leak
Perhaps the gross leak code has to do with the vent valve. Find the vent valve. It should be near a rectangle evap canister. Maybe under the bed. The small vent line from the fuel tank will go to it. The solenoid is near the cansiter. With the key off the valve will be open. With the key on it should be closed. You may try disconnection the hose and blow through it with both key off and on and see if air will pass through. If the valve has died and is stuck open, that can be the huge leak.

If it is not the leak then a smoke machine should be used. Easier than searching the lines for bad o-rings, splits, or whatevers.

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 codes2.gif, 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 vacuum2.gif
