P0456 Indicates that there is a small leak in the evaporative emission control system. It often appears with or is related to other codes, such as P0420, P0441, and very often P0440. P0456 is normally not an immediate threat to the driveability of your Outback. Certainly, anytime the service engine soon light is on, it’s good to deal with it ...JohnGD said: P0456 is very difficult to locate. It's a leak through a hole about 1/2 the size of a human hair. If you suspected impact then I'd check around the canister and the hoses around there.

If the pressure comes out of parameters, it detects it as a leak which would cause an excess amount of EVAP emissions. Your DTC states that it is a 'Small Leak'. There are a few DTCs for EVAP leaks.The leak-detection process is very similar to the one described above, with a few exceptions. Obviously, the quantity of leak decay is tighter, and if a .020-in. leak is detected during a cruise test, the PCM performs a confirmation test with the vehicle sitting still at idle speed. The new fault code added is P0456, for a .020-in. small leak. nitto trail grappler reviews The EVAP monitor is non-continuous. This means the system is only tested and monitored under certain conditions.

Changed gas cap to an OEM and still kept getting code.An EVAP (Evaporative Emission Control System) system leak should be taken seriously, although the severity can vary depending on the size and location of the leak. While a small leak may not immediately affect the vehicle's performance, it can lead to increased emissions, reduced fuel efficiency, and potential issues during emissions tests. zillow clairemont I have a P0456 that will come on only after my 2009 2.4l Patriot after it has sat out overnight or a few days when there is heavy rain (1 or more inches of rain).
