Question about 2001 Hyundai Elantra

Open Question

I have a p0440 code on my 2001 elantra 4 cyl. I checked the gas cap (replaced about a year ago) it looks good. A friend lent me a smoke machine. I couldn't find the test port, so I hooked it up to the vac line on the bottom of the purge valve that goes into a steel line to the back of the car. I had smoke coming out of the charcoal canister vent. Could the valve on it be the problem?

P0441 is Evap Emission Incorrect Purge Flow; the repair you are describing is easy, and should correct the P0441 restricition...I would anticipate no large problems.

SOURCE: Mustang GT 4.6 EVAP Canister Purge Valve Location?

You will need to remove the right front wheel & wheel well liner. The canister purge valve is behind the cover. It should have two tube going into the bottom and one on the side near the top.
You can fix it!
If this helps you out please rate me!

SOURCE: I have a 2004 Avalanche, 49K mileage, code PO446,

That is an EVAP code. its a vent control code. you can manually test it by powering it up if you know where its at. i cant remember exaclty where its at off the top of my head but its only 2 wires. using a volt meter you want to make sure power is getting to it, but you cannot activate it without dealer scan tool.hmmm if you can figure out which is ground and power when you give it 12 volts it should click. meaning your vent solenoid works and you have wiring problems or its leaking.

EVAP problems are hard to finde with out scanners. you can change the vent solenoid and hope it fixes it. but a code points you to the direction of a problem. hopefull its not wiring problems. in the northern states with snow. ice can pull out wires and also get clogged in the vent solenoid and lock it up. its either wiring or bad or a leaking solenoid. check condition of wires. if they look good try a vent soleniod.

if that doesnt fix it after a engine light reset and 2 weeks or so. then goto dealer. you need to reset it after repair. light will not go off on its own.GOOD LUCK

I have a liltle light in the panel of my car (Hyundai Elantra 2001) that says check engine and the scan problem is the famous ... P0440 EVAP System please help me i really want to eliminate the error !!!...


tightening your gas cap can sometimes fix this problem. Think if the light came on after buying gas.
If not it's usually the rubber seal around the gas cap. Just measure and replace with a similar rubber seal available at any hardware/auto parts store.

I have a 2001 grand am se p0440 code comes up


This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
Causes:

p0440 code means that the evap system has a leak. This could be caused by a bad or improperly installed gas cap. Either that or the purge solenoid has failed or the canister is plugged and not working properly.
