Replace the NVLD (natural vacuum leak detection) pump. Remove the right rear tire and inner fender splash shield. The pump will be attached to the vapor canister.

Po016 and po441


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.

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
item

Codes po452 and po453


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.

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.
