P0457 Evaporative Emission Control System Leak DetectedIt means there is a vapor leak between the gas cap, tank, and engine.P0457 Evaporative Emission Control System Leak DetectedIt means there is a vapor leak between the gas cap, tank, and engine.
evaporative emission control system leak detected
Replace the gas cap first.
Evaporative Emission Control System Leak Detected(Gross Leak)....meaning large leak within the fuel evaporative system. Sometimes this code can be caused simply by just a faulty gas cap.
In many cases the fuel cap is at fault, or a cracked vapor/vacuum hose.
Evaporative Emission Control System Leak Detected (small leak) It is a very small leak in your EVAP control system. In fact it could be as small as 0.04' in in diameter.
You are looking for a vapor leak from the fuel system. Check the gas cap, lines and hoses from the tank to the engine.
P0442 Evaporative Emission Control System Leak Detected (small leak)
Trouble code P0456 means: Evaporative emission (EVAP) control system leak detected (very small leak)
Trouble code P0442 means: Evaporative emission control system, small leak detected
Trouble code P0455 means:EVAP Large Leak DetectedLarge vapor leak in the evaporative emmisions systemTrouble code P0455 means: Evaporative Emission System Leak Detected (gross leak/no flow)Large vapor leak in the evaporative emmisions system
It is a vapor leak in the fuel system. Starting in 1996 vehicles check for leaks down to .020 inch.
