SOURCE: I need to know what part needed for a Po440 Code?

Most likely not a part. Make sure your vacuum supply to your leak detection pump is not disconnected. This is the cause 9 out of 10 times. If not, check for power and ground to the LDP, or the purge valve.

My 02 camry le failed emmission test whats wrong error codes po440, po441, po446, po420


You have codes for a failed exhaust converter,PO420,
EVAP System problem PO440,Incorrect Purge Flow PO441,
Evap Vent Control issues,PO446

Your car is all messed up

That should have been all checked, BEFORE you spent time
in line for inspection

If all the codes are for real & not a false report

You will need new spark plugs,ignition & fuel checked,
new exhaust converters,new evap purge valve,new evap
vent solenoid & possibly vacuum leaks resolved

You either bought someones neglected vehicle or never
do a thing but drive it

May be easier to get a different vehicle,your repair bill
will start at $1,000 & go up, from not being proactive & taking
care of what is required in owning any vehicle (lack of knowledge)

You will need the oxygen sensors also & no, they won't fix the
amount, of what appears to be several failed items, all at one time

So much for Toyota being better than other vehicles

Toyota seinna po440, po441, po446


you have to understand that there is a leak in the system other than the gas cap for the evaporative system. The system needs to be professionally closed, and smoke introduced into to find the leak, and a through component check, eg.. purge valve vapor canister vent solenoid all functioning correctly

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.
