However, this does not indicate a malfunction. The cost to diagnose the p0457 subaru code is 1.0 hour of labor. Manual shift joined nov 23, 2019 1,581 posts #9 · nov 28, 2019 i know this is an old post but wanted to say thanks.
This Evap System Leak Will Cause Fuel Vapors To Escape Into The Atmosphere.
Its been asked about a few times over the years. Last week the new owner of a 2012 subaru forester contacted me about her a/c losing refrigerant. Emissions pump having to do with the vapor control in the fuel system.
It Got Regassed 4 Months Ago And She Wanted The Issue.
The idea behind this method is to use a calibrated digital thermometer and place it on the bottom of your fuel tank. When you turn on your vehicle, the temperature reading will be recorded. It is similar to p0455 (large leak) and p0456 (small leak)

It’s always a good idea to take a look at the gaskets and connections in the exhaust system before looking for a failing pipe, manifold, muffler, or catalytic converter. The system can detect extremely small leaks between the fuel filler cap and the evap canister valve. This code references a number that is given to you when you plug your forester into a obdii scanner.
Every Subaru Forester Has A Vacuum System That Performs A Wide Variety Of Functions.
Evap system leak detected tells you that your silverado or sierra's fuel injection computer has pressurized the evap system to test for leaks and has found one. The evap system captures all fuel vapor from the fuel tank and sends them to the engines intake in order to be ignited in the normal combustion process. The subaru forester’s throttle body and throttle plate/butterfly valve will typically be cleaned of dirt and grime at the same time.

Most likely is the gas cap (loose or its internal valve) or the main breather from tank to top of filler neck, also not sure where the closure valve for testing is on a suabru (most are at the back of the car near the tank) so nothing engine side of that can set the code. Your subaru forester has a vacuum leak. If it only happens when it is off, then this is likely a solution.
