you use a smoke test to lightly pressuize system and search for leak in system also use a computer to activate some of the system parts such as purge valve or caniter close valve look at scan tool results to confim propper operation
An EVAP system is the system in the car that retrieves fuel vapors from the gas tank, as well as the rest of the fuel system. The EVAP system will then recycle these vapors so they can be burned in the engine. The EVAP port is a test port where a vacuum can be attached to check for leaks in the EVAP system.
take it off and suck on it
Small leak in the evap system. You need to do a smoke test
po440 is a problem on cooling system or fan in radiator
v8 becaus it is a powerful engine go test it go drive in a lake.
According to the Internet Auto Guide, the Accent has a 5-star crash test rating for frontal impacts. However, side impacts only rated 3.5 stars, and rollover impacts were 4 stars. For more information, visit http://www.internetautoguide.com/crash-tests/09-int/2010/hyundai/accent/index.html.
From the PCM. You'll need a repair manual to determine which wires to test
Check the battery ground cable and make sure it is clean and making a good ground.
P0456 = Evaporative Emissions System - Small leak detected. There could be a small leak the size of a pin hole somewhere in the EVAP system. Finding this leak on your own can be difficult and almost impossible without the use of a smoke machine.A good place to start would be to spray a little carb cleaner on a shop rag and wipe down the fuel filler neck seal area with a clean lint free shop rag and replace the gas cap with a new one. If that doesn't do the trick, eye ball the EVAP system carefully front to back looking for trouble spots. If that doesn't help you will need to have a garage do a smoke test on the EVAP system. There are some videos on You Tube where people have built there own home made smoke machines to test automotive EVAP systems. You will need to understand how the EVAP system works to properly test it for leaks with a smoke machine. Good luck.
Up on top the engine, passenger side assuming the engine is a 4.3 V-6. The year and engine info would help. You can also look for the small green plastic cap within the engine bay. The valve under the cap is a test port for the EVAP system. Follow the line to the engine from the test port. It will lead you to the EVAP purge valve.
A P0442 indicates a EVAP System small leak. While this may be caused by a loose or worn gas cap, as is often the case, it usually points to 1 of 2 other problems. The "small leak" diagnostic indicates a leak as small as .020 inch in diameter which means it could be a leaking line within the evap system. It can also be a stuck open EVAP Vent Valve or a faulty Fuel Tank Pressure Sensor. This diagnostic has to be done by a shop with a scan tool capable of reading Tank Pressure voltage and/or performing a EVAP System Smoke test to find the leak.
No, but you have to understand this accent for the listening test.
