Question about Cars & Trucks

Not sure why the previous post talked about an oil control valve, this is an EVAP code...
DTC P0454 EVAP EMISSION SYSTEM-PRESSURE SENSOR INTERMITTENT
Probably either a bad connection or bad EVAP pressure sensor.

more than likely you have a bad oil control valve if in fact you have an 06 sonata. They are chain driven engines... You can ohm out the valve and get a good reading even when the valve is bad. Pull it out and check to see if it is clogged, if it is thats more likely your problem. If it is clean, go ahead and replace the valve. Hyundai calls them the oil control valve (OCV) and usually located on the head close the the variable valve sprocket.
