That is an evap system leak.

The evap system controls recirculation of fuel vapor in the engine intake manifold .
Check first the fuel cap, ensure that is well closed, then remove and inspect it.

Have a vacuum test done, or test for vacuum leaks using a Vacuum/Fuel Pump Tester Kit
If there is no leak, then the problem can be a storage canister or a defective purge solenoid.

Chrysler p0456 code


Possible causes - Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Evaporative Emission (EVAP) canister or fuel tank leaks
- Evaporative Emission (EVAP) system hose leaking
- Fuel tank leaking
P0456 Chrysler Description The Evaporative emissions system is design to prevent the escape of fuel vapors from the fuel system. Leaks in the system, ca allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage. During the self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

P0456 on chrysler 300


It is a very small vacuum leak in the evaporative emission control system.
Until that is fixed, it will keep showing. The best way to find the leak, is to take it and have a smoke test done on it to pinpoint the leak, otherwise you will go nuts trying to find it and replacing vacuum lines you don't need. All they do is inject smoke into the emission system and where ever the smoke comes out, is where the leak is.

My 2007 Chrysler Sebring will not pass smog check . It has 74, 000 miles on it. PQ457 Evaporative Emission System Leak (fuel cap loose/off) PQ455 Evaporative Emission System Leak (large leak) PQ456 ...


This depends on the problem , like a bad gas cap is not covered but so what a cap is cheap, take it to dealer and let them fix it for free or very cheap. most of the time its a valve, purge valve or vent valve, these are covered, take it before you hit 80,000. good luck.

At least the cap isn't loose for the gas tank.

I would clear the code with an OBD-II Scanner 'erase code' button, and see how long it takes for it to come back.
