Engine light still on

p1423 p1411
u either forgot to put the hoses at the air motor or air motor not working.the location is at the passenger side in front of engine behind bumper and right beside the a/c dryier.looks like a blower....
p1227 can not remember......
check light went on when the engine got warm?

You could possibly fry all the main computer controllers in your car from reverse hooking up jumper wires.

Hi Roza,
I think you'll have to replace more than the air flow sensor. I think you'll also have to replace the management system. I believe the engine you've used in fact doesn't use an air flow sensor, but instead uses a manifold absolute vacuum sensor which is incorporated into the management system (The engine management computer). The electronic system used for the one engine is not compatible with the other as far as I know....You may find you have to do a good amount of rewiring to the vehicle!

This is what I got from a google search;
p0441 (vag 16825) = EVAP Emission Contr.Sys.Incorrect Purge Flow
The evap system has several valves and solenoids that control purging of evap gases from the fuel system. Most likely one of these valves is not opening/or is stuck open. If something is stuck open it could actually lead to the above 16839 fault code.
Hope that helps.

get the vehicle scanned for the trouble code most auto stores such as auto zone/advanced auto scan for free check ur local area the check engine comes on when the computer senses a problem or something is not reading right if u want when the code is read the store or mech can and usually do reset the computer

It could be that the thermostat is stuck in the open position thus providing maximum coolant flow through the engine when the engine is still cold, ie from a cold start. (The thermo should close when the engine is stopped and cold and it opens up once the coolant temp increases and the engine has been running for a few minutes.) Once the engine is hot maximum coolant flow between engine and radiator is normal.

Do you also find that your heater takes a while to provide warm air to the cabin in winter when you notice this condition?

If you do not know when the thermostat was last changed then I would suggest you change it. ( If it malfunctions and sticks in the closed position you will really have a problem). The radiator/engine coolant could no doubt do with a flush and change in any event as it should be done every 2 years. If you don't know when it was last done - do it. Cooling systems tend to be a neglected part of essential vehicle maintenance.

PO432= 1 OF THE SENSOR IN THE EXHAUST SYSTEM if u stand in front of engine to your rt under the car should be a oxygen sensor just unplug it and put a new one.....(bank2)
PO441 = Evaporative Purge Flow Monitor check your fuel cap and replace all of your vacuum hoses because they can be damaged or plugged this should fix it.
So good luck to ya....

What I would suggest is taking the car to an autoparts store and have them scan the computer for any fault codes that it has stored. Most parts stores will do the scan for free. That should eliminate the need for speculation. It could be an emission related problem or it could be something totally unrelated. Better to get the codes to narrow down what the computer has noted. Hope this helped and best wishes.
