Replaced catalytic converter and o2sensors
The codes should be addressed in the order they show up, so starting with the P0443 (it's a zero not an o after the P, the P refers to a powertrain code).
Have you replaced the purge valve itself, often times this will rectify the trouble.Open the gas cap after driving a while , do you hear a "whoosh" of pressure release? If so likely the valve itself is defective.Replace it reset the MIL and drive to see if light comes back on, if it does ,rescan to see if 443 is still present, if not then move on to new first trouble code.
(fyi)
To cause a P0443, there has to be a problem with the purge control CIRCUIT, not necessarily the valve. Usually they are a unit housing the valve and the solenoid as an assembly. Or it could be comprised of a separate solenoid with vacuum lines to a purge valve. That said, it could be any of the following: Bad purge solenoid (internal short or open) Wiring harness chafing or rubbing another component causing short or open on control circuit Connector worn, broken or shorted due to water intrusion

P0443

P0443 - EVAP Control System Canister Purge Valve Circuit Malfunction The PCM monitors the state of the EVAP canister purge valve circuit output driver. The test fails when the signal moves outside the minimum or maximum limit for the commanded state. VPWR circuit open
EVAP canister purge valve circuit shorted to GND
Damaged EVAP canister purge valve
EVAP canister purge valve circuit open
EVAP canister purge valve circuit shorted to VPWR
Damaged PCM
To verify normal function, monitor the EVAP canister purge valve signal PID EVAPPDC (or EVMV for electronic valve) and the signal voltage (PCM control side). With the valve closed, EVAPPDC will indicate 0% duty cycle (0 mA for EVMV) and the voltage approximately equal to battery voltage. When the valve is commanded fully open, EVAPPDC will indicate 100% duty cycle (1000 mA for EVMV) and a voltage drop of 3 volts minimum is normal. Output test mode may be used to switch output ON/OFF to verify function.

P1451 - EVAP Control System Canister Vent Solenoid Circuit Malfunction Monitors the canister vent (CV) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified canister vent duty cycle by PCM command. VPWR circuit open
CV solenoid circuit shorted to PWR GND or CHASSIS GND
Damaged CV solenoid
CV solenoid circuit open
CV solenoid circuit shorted to VPWR
Damaged PCM
To verify normal function, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage (PCM control side). With the valve open, EVAPCV will indicate 0% duty cycle and the voltage approximately equal to battery voltage. When the valve is commanded fully closed, EVAPCV will indicate 100% duty cycle and a voltage drop of 4 volts minimum is normal. Output test mode may be used to switch output ON/OFF to verify function.

Why you replaced catalytic converter,O2 sensors OK
SOURCE: Check engine light comes on. p0171 and p0351 codes found
From Lusty Kid:
I know the economy is bad, but change all of the plugs. Check your PCV Valve hose, 150 rottens them out allowing air to be sucked in, thus all kinds of codes.
Depending on mileage. Dismount the EGR valve and clean passages. If you are really good dismount the throtle position sensor body and clean out passages with Choke Cleaner., dismount where the EGR valves connects to the engine, clean out passages. Also check the hose thats behind this mounting to ensure is not clogged. If clogged clean it out. If not replace it. Is about 1.5 ft. long, connects to the PCV Valve Hose.
When is the last time you change your harness. Can't remember??? Replace it. Good Luck
SOURCE: Check Engine code P1409
clean the egr valve port on intake use piece of clothes rack clean the built up carbon on inside of port.
SOURCE: locating vacuum canister and testing it
The purge solenoid should be in the hard plastic vent lines that run under the tube between the intake and the air filter, ablove the transmission, it is common for vibration holes to be worn in the hard plastic tubes causing a vacuum leak. The purge solenoid is small and it has an electric wire coming from it. I 'think' your canister is in the front lower left corner under the hood, you may have to remove splash shields to see it. The problem is most likely in the hard plastic lines at the solenoid. Let me know if this helps.

maybe a fuse is blown? did you have the mechanic check the fuses? or even check all your relays and wiring?

sorry but your code reader is not reading manufacturers codes ,if an american market vehicle then you should be able to read them but if this is a europeon model then how did you manage to get this code??
P0235....Turbo/Super Charger Boost Sensor 'A' Circuit
this is a generic code if its any help
