P0449 code means that the EVAP vent control valve is malfunctioning due to an electrical issue (high resistance) or mechanical issue (sticking valve). One obvious symptom may be a noticeable fuel odor but usually no change in car performance. P0455 code means that there is a huge leak in the system.

|P0442 SUBARU code tech notes The P0442 code means that the control module has detected a small leak in the Evaporative Emission (EVAP). Loose fuel tank filler cap is the most common cause that triggers the P0442 code.

A perfect example of a EVAP system that does not require the Purge Valve is the JDM Subaru ej207. This model still uses the same EVAP purge solenoid, but the mess of hoses is cleaned up considerably (only 2 hoses now). Diagram A and B cars can be setup in the identical fashion, although it does not apply to diagram C cars.

The EVAP system has three primary operations: storing fuel vapors, purging fuel vapors, and self-monitoring. Storing Fuel Vapors. The vapor canister is the focal point of the EVAP system. When the engine is off, fuel vapors from the gas tank are stored in the canister.

Evaporative Leak Check Module consists of the pressure sensor, the reference orifice (diameter of 0.02 inch), the vacuum pump which introduces the negative pressure into evaporative emission system, and the switching valve which switches the passage to introduce the negative pressure.

So a P0442 code typically means there is a small (under 0.04") leak in your EVAP system. A little bit of background: Your EVAP system works to contain all fuel vapors and preventing them from going into the atmosphere. The charcoal canister stores fuel vapors for the engine to be burned off later in the engine.

Typically the EVAP test is a series of tests run at different operating conditions and temperatures. From what I've read you will probably need to run a couple normal driving cycles getting the ECT up above 176F and at least one start from a dead cold (parked overnight) cycle. Fuel level also seems to be important, some manufacturers require ...

Read how the EVAP system works below. The EVAP System is sealed. As you drive and conditions allow, the engine computer (PCM) tests the EVAP system for leaks by monitoring pressure or vacuum inside the system. The code P0442 indicates that the engine computer (PCM) has detected a small leak in the EVAP system. Symptoms:

All of the EVAP fuel vapor purge systems are designed to do the same thing: manage fuel vapors while the fuel tank expands and contracts, and manage the high volume of vapors created during fuel fill up. While technically an emissions system, it's not like a smog pump from back in the day.

The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine. Symptoms Possible sumptoms of OBD code P0455 Subaru
