This code is certainly related to a evaporative emissions leak, if you cannot see any broken or damaged components at the rear of the vehicle you will need to have the evap system tested for leaks this is performed by using a smoke machine that will induce a non toxic smoke into the fuel system and emmissions lines to determine the source of the leak. Please rate this info, this will help me out thankyou RJ

Why does my 2004 pontiac bonneville start up then shut off after 2-3 minutes?

Remove the O2 sensor on the back side of the engine exhaust manifold. Start it, if it runs for more than the 2 or 3 minutes, replace the catalytic converter. 455 is a purge solenoid code. This wouldn't keep the car from running.

How do I clear the code PO455 after the repair?

You would need a scanner or code reader to erase the code.
Keep in mind code 455 is for a large leak so it could be something other than the gas cap.

EVAP Leak Detected (Gross Leak)

the tank has a vent system.
it is tested constantly running for being sealed.
the top cause 99,99% is the gas cap is, loose, missing or wrong kind or bad.
if the gas cap is good. then the system has a breach.
we use a leak down tester to find those leaks. easy.
cracked vent hoses?
do you want to do tests? do you have tools?
if not.
reset the code and use a new cap.
does 455 come back.
yes, then the tests must be done. guessing will no work
visuals can work, looking for cracks.

What are the code manings of P0455 and P0457 for a 2003 ford mustang gt?

Both codes are for major leaks in the Evap system which vents fumes from the gas tank to the engine.
Code 455 is for a major leak, and code 457 is for the gas cap which could cause 455.
The codes can set if you run the engine with the gas cap off, or there may be a problem with the cap or other component.

Code pd 455

It means a large evaporative emissions leak. It could be a leaking or broken vacuum leak, or a bad seal on the gas cap even. Clear the code and see if it comes back. If so you can replace the gas cap and inspect vacuum lines for leaks. Replace any that are questionable.

2000 Dodge Intrepid with PO455 code and stalling.

A code 455 most likely one or more of the following has happened
a loose or bad gas cap
a non-conforming gas cap
other leaks or damage pieces in the evap system

Inspect the evap system for cracks or breaks in lines listen for vacume leaks or strong gas fume smell and fix all lines you find that are damaged ..I know you say you put a new gas cap but make sure it a conforming cap..Hope this helps

Error codes p0442 & P0455

Those are both Evaporative Emission Control System related.
442 is a small leak has been detected.
455 is a bigger leak has been detected.
Check all your connections, (electrical & vacuum lines) as well as check for any cracked, loose vacuum hoses in the system, as well as clean "O" ring on your gas cap well and threads in filler pipe & make sure gas cap is tight. Do the gas cap first & see if codes dissappear, but it may take a new gas cap. These codes commonly appear shortly after getting gas, due to cap not back on tight.

Service engine soon light came on, the codes was p0335 and p0455

Code 455 happens when the gas cap is loose or gone. Replace the gas cap. To get the service engine light to turn off you need to reset the computer by unhooking one of the battery cables and then reattaching it.
