Welcome to Fixya

All of the codes are for Evaporative Emissions System.

P0440- Evaporative emissions system fault- just saying there's something wrong with the system.
P0441- Evaporative emissions system- Incorrect purge flow- saying that the system isn't purging the raw fuel vapors (hydrocarbons- HC) as well as it should.
P0446- Evaporative emissions system- Control valve circuit low- there is a valve, usually located on the charcoal canister at the rear of the vehicle, that opens to allow fresh air to enter the evaporative emissions system as the engine vacuum purges the fuel vapors from the charcoal canister and closes when purge is not needed to prevent leakage of those fuel vapors to the atmosphere (HC is a greenhouse gas and is regulated as such by the fed gov't).

Since there is an incorrect purge flow code and the control valve code together, the vent control valve has failed (causing the P0446) and is not opening to allow fresh air into the system to displace the air from within the system that is being pulled to the engine. Since you have no fresh air entering the system, the engine will pull a vacuum on the system instead of the vapors "flowing" into the engine (causing the P0441).

If the lid is too high, the latch / keeper needs adjusting downward -- loosen, move it down, retighten, test -- repeat until proper adjustment is achieved.

If you are in front of the engine, in the rear left, by coil or plug #1, pull the hose and pcv, in some engines you need to un screw it. If you need further help, I’m available over the phone at https://www.6ya.com/expert/flavio_517b938f50183b92

how much did you add. your car being a 2007, you shouldnt have to be adding coolant, unless there is a problem like a leak

Hi!!
The manufacturer recommends 6 2/5 qts. of High Performance or Synthetic 5W30 Engine Oil.
A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

This is the check engine light. Hopefully, your gas cap is loose or missing. This link might help. If not you can google "check engine light troubleshooting. Hope you find it.

This symptom is usually due to worn valve guides. The guides allow oil to drip into the manifold ports. When the engine starts, it has to burn off the oil, but the leakage is so small that it becomes unnoticable after the engine has been running. To prevent this, the cylinder head(s) must be removed and the valve guides either knurled or replaced. Please let me know if you have more questions.

p0352
Ignition coil B primary or secondary circuit malfunction
p0300
Random/multiple cylinder misfire detected
p03001
cylinder no.1 misfire detected
p0306
cylinder no.6 misfire detected
check you coils and spark plugs
make sure they are in good shape. check you spark plug wires also.

A flashing check engine light indicates a cylinder missfire. A evaporative emissions leak (the result of a bad gas cap) wouldn't cause a rough running condition. How many miles are on the vehicle?
