Po447 check engine lamp is on

code p 0447 refers to evaporative emission (EVAP) system vent control---open circuit ===causes --wiring open circuit--EVAP canister purge valve---ECM
code p 0453 refers to EVAP pressure sensor ---high input===causes --wiring short to positive ---EVAP pressure sensor --ECM

doubt check the gas cap will fix it, that usually throws a gross evap leak code. that code refers to the vent control circuit, specifically to the connectors at the evap canister behind the passenger wheel. it\'s pretty easy to get to, so get a nice flashlight and check the connector, my bet is that some water (as in the linked post) got in the connector or the connector itself is damaged.

Let us know if that worked. there is also a vent at the rear of the car where it expels the waste. What was the code?

Here's a link to your code YVON.

it a bad evap vent control solenoid code

The purge valve solinoid is on top of the engine to the left of the alternator. It has an electrical connector and two smallish hoses, one to the intake manifold and one to the purge valve. Inspect both hoses for cracks and dry rot. Make sure you get them installed correctly. The one closest to the solenoid is to the manifold and the one at the end to the valve.
Disconnect the battery before replacing the valve.
A Common cause of OBDC errors. Some code readers can cycle through solenoids, tests AutoZone may not trouble with.

P0447....Evaporative Emission Control System Vent Control Circuit Open

its a fault for the vapour control circuit and according to teh read out it would appear that the motor isnt connected but its not a serious fault and you can drive the vehicle with no problem

PO 447 has to do with the EVAP emissions control circuit. This is what 'sucks' the gas fumes from the gas tank. The first thing to check is the gas cap. Is it tight? Is the seal cracked? If not, the EVAP purge valve may be bad or the rubber hose that goes to it has a leak.

Research revealed no data availabe for code P0447 - doesn't exist for Hyundai Accent.

There are codes P0446 and P0445, but nothing with P0447.
