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

DTC CODE PO455 2000 BEETLE WITH 38,000 MILES


Hi.

The DTC PO455 means "Evaporative System Emission Leak". The evaporative system is where gases evaporating from tank are collected and directed to the engine where they get mixed with fuel from pump and air.

P0455 is often caused by a defective fuel cap. The fuel system in your Beetle is pressurized. If the cap is defective it will allow gases and air out triggering the code.

Change the cap first.

If the fuel cap does not fix the problem then there is effectively a leak. That is usually caused by a broken evap system hose. In that case the parts in the evaporative system must be tested. The repair should not be expensive.

Regards.

Have dodge caravan se with 83.000 miles on it engine light is on with a code po455 po442 and car stalls while driving but will restart again, thats the only code that comes up.


Hi:
These codes are part of your evaporative emissions system, and can be a real challenge to troubleshoot and repair. Most people start with a new gas cap, but end up checking hoses, charcoal canister, and evap control solenoid before all is well.

I know this isn't the answer you were looking for, but at least some direction!

Failed Emision test


po442 is evap emission control system leak (small) 1 of the lines for emissions is leaking. po455 is-- emission control system leak (large). turn off light with code scanner after it is fixed.

Check engine light comes on


"po455 large leak" means that you are not maintaining positive pressure in your fuel system. Have a mechanic do a "smoke test" on the fuel system. Could be as simple as a loose gas cap...

Code PO442 & PO455 on a 2003 Dodge Caravan with 3.3 engine


The problem is most likely to be with your vacuum line they put cheap rubber hose for this purpose. You should find a diagram at the front of the vehicle trace the hoses by this diagram. You most likely will find a bad piece of hose.
