Check engine light is on
EVAP Emission Control System - Small Leak Detected (1.0 mm). This code can be set when 1. fuel filler cap is not completely tight, 2. when various hoses get punctured or the canister close valve does not seal completely, 3. there is an actual leak in the charcoal canister, fuel tank, or other EVAP system component, 4. if any one of these components are malfunction (a), fuel tank pressure sensor, (b) purge control solenoid valve, (c) canister close valve, or (d) fuel cap. An engine vacuum leak would not set this code.
Solution: Take the vehicle to a Hyundai Dealership for proper diagnosis/repair.
Cannot pump gas in a 2001 accent pump shuts off have to let gas drip in slowly

Code 442 indicates a vapor leak in the EVAP control system. Fuel vapors are routed through hoses to the EVAP charcoal canister, then via purge control valve, are rerouted through intake when engine running. Bad gas cap seal is the usual culprit, which you can try cleaning the seal & filler neck where it screws in, then erase codes & try again & see if it comes back, or may require new gas cap. Other areas to look is at hoses running to & from canister & purge valve for any crack that may be a source of leak.

check all hoses on vehicle especially around canister and make sure u have a factory gas cap
The canister purge solenoid is part of the evaporative emissions system. When it is commanded "open" by the PCM (computer), it allows fuel vapors in the fuel system to enter the engine. This solenoid basically acts as a valve regulating fuel vapor flow to the air intake system. By burning these vapors in the combustion process, the evaporation system helps to lower overall vehicle emissions. The solenoid circuit refers to the wiring used to control the function of this solenoid, and usually runs between the solenoid and the vehicles PCM.
any defect in the above mentioned canister working will cause your problem to happen
Testimonial: "Thank you, exactly what I needed to know!!"
SOURCE: OBD 2 codes p0442 and p0455, also smell of fuel from ventalation system
These codes indicate a leak(s) in the fuel system, it can be anywhere, you will have to crawl under and try and see where the leak is, you will need a scanner to turn off the light after repairing the leak(s)

hello po442 ,po455,po456 is leak detected possible, check the gas cap , basicaly you have a leak that is larger than 0.020' and smaller than 0.040' in the gas evaporative system use your nose to find this one thanks

You have a vacuum leak. This means that you will need to go through all of the vacuum likes and make sure they are connected and not broken. If they are broken buy new vacuum line, its like less and $1 per foot. In your case if you can I would replace all of the vacuum lines if they look cracked and old.
