Purge Control Valve Problem

The "Purge Control Solenoid Valve" is the "Purge Control Valve".

Rough idle is a typical symptom of something amiss with the purge control portion of the evaporative emissions system. It could be the valve itself is not operating correctly, the evap canister (vapor canister) may be leaking, or full of raw gas instead of vapor, or maybe even the purge control valve is getting a faulty signal from the ECU.

The soleniod is checked by applying a voltage to it and checking to see if it closes, or opens (I'm not sure if its un-energized state is normally open, or normally closed). If the valve is bad it is a no-brainer to replace.

The vapor canister can be removed and checked to see if it is full of raw gas (not supposed to be), but checking it for leaks is a bit involved, and probably requires equipmet not normally owned by a home mechanic. Vapor canister failure on cars with a lot of miles is common. Replacement is the fix.

Of course if the ECU is not sending a purge signal to the valve correctly, figuring out why may proove difficult, and possibilities could even include a faulty ECU. I expect this is unlikely though.

It's a $20 part. I first would change pcv valve because it can give same error if it's plugged up. You can always remove it and shake it. It should rattle around real easy. If not, it should be repalced

I'm receiving an Error code po441, I took it to the dealer who replaced the EGR valve and reset the engine light and cleared codes a week ago, now my engine light just came back on with same code


Some dealer you got there

PO441-EVAP System --Incorrect Purge Flow

They may have found an EGR Valve issue,
but they certainly blew off the EVAP Code

I would guess you have a bad EVAP Canister
Purge Valve or some other purge control

Engine light on PO441, PO344 and PO440 were the codes that came up. 2003 PT cruiser


P0440 and P0441 are refering to the NVLD pump. It is in the rear on the right side up near the fuel tank. P0344 is your cam position sensor on the rear (drivers side) of the cylinder head. The P0440 and 441 are probably why the check engine light is on and the 344 was stored from a previous event. Either way they are two different and unrelated problems. The NVLD (natural vacuum leak detection) pump is an emission item with no effect of the way it runs however it will keep the engine light on. The cam sensor will keep it from starting or intermittently run bad and not necessarily turn the light on. Both parts are easy to change. I hope this helps.

if the air filter was recently inspected or changed, look for the vacuum hose to be disconnected from the valve located on the air filter cover. another source may be the gas cap either loose or with the tether strap caught under it preventing a proper seal
