Chrysler 300, 2005 Codes PO452 and PO441 What needs to be replaced

Here's a link to code P0102,P0441 and P0340.

Codes have nothing to do with parts

You need to study OBD2 Systems on the internet,
as well as look up those codes & the causes

Google them

( 1998 Toyoya Camry OBD2 PO441)

PO441---EVAP System Incorrect Purge Flow
PO440---EAVP Control System Malfunction
PO446---EAVP Vent Control Circuit Malfunction

I think a repair shop is your best bet to smoke test
system & resolve

PO440-EVAP SYSTEM NO FLOW DURING PURGE.CODE PO PO452 - FUEL TANK PRESSURE SENSOR CIRCUIT LOW INPUT.

Code 16 is for a problem with the cam timing on bank one, and code 441 is for a problem with the EVAP purge system performance.
The two problems should not be related.
The first problem could be a faulty cam sensor or wiring issue, the second problem could be one of the valves in the system that vents the gas tank.
You may need to get a shop manual or repair book for the procedures to troubleshoot the codes.

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
item

both codes point to the fuel tank evap pressure sensor. High and low input faults.
Try clearing the codes first and seeing if they come back

You may have a vacuum leak, cracked or open vacuum line or faulty sensor.

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.

evap emission control system fault-po441, po742 is--torque converter curcuit stuck on, for this code, check torque converter clutch switch..

p0446 is an evap code for incorrect purge flow, check the rear vacume switching valve. its above the rear sub frame
