P0455Evaporative Emission System Leak Detected (Large Leak)

The computer ran a leak test on the sealed fuel-vapor system and found a large leak, meaning the system could not hold pressure or vacuum. The most common real-world cause is a loose, missing, or bad fuel cap. Fuel vapors that should be captured are escaping to the air instead of being burned.

Ամենատարածված պատճառներն են՝ Loose, missing, or faulty fuel cap (most common), Cracked, disconnected, or damaged EVAP hose, Faulty EVAP vent or purge valve stuck open, Damaged or leaking charcoal canister, Damaged fuel filler neck or seal։

Սովորաբար անվտանգ է կարճ տարածությունների վրա վարել, սակայն շուտով ստուգել տվեք։

First tighten the fuel cap until it clicks (or replace it if worn) and drive a few cycles to see if the light clears. If it returns, have a technician smoke-test the EVAP system to find the leak; the car is safe to drive in the meantime.
