code p0447 keeps coming up after resetting computer
Expert:  Jay replied 4 months ago.

Hello my name is ***** ***** thank you for your question.

That code is for a Evap Vent control valve and will not cause your issue.

Do you have a full blown scanner?

Customer: replied 4 months ago.
no only a code scanner

Where did you get the MAF sensor you installed?

Customer: replied 4 months ago.
I got it from another 2005 Nissan maxima so I just used it to see if that was the problem. If I would of purchased it I could not returned it that's why I thought of borrowing my friend's before buying one.

Did it do the same thing before you changed the transmission?

Customer: replied 4 months ago.
do you think it could of been that MAF that I used from an 05 on would that be different from the 08?
Expert:  Jay replied 4 months ago.

I think they are the same MAF sensor. Has fuel pressure been checked and exhaust checked for any restrictions?

Customer: replied 4 months ago.
No, I haven't checked fuel pressure. How can I check the fuel pressure and the exhaust?
Expert:  Jay replied 4 months ago.

Fuel pressure is checked with a gauge, and the exhaust is checked by lowering the flex pipe to ensure the catt converters are not broken up causing a exhaust flow restriction.

I did what you said but got this code p0081. Does the computer control this piece? We also changed the intake valve control solenoid bank 2, even disconnected and it still did the same thing. Do you think my computer could be bad?
Expert:  Jay replied 4 months ago.

I know a trick to determine if the computer is bad. You said you changed this solenoid? Do you know which side is Bank 2?

Customer: replied 4 months ago.
the one closer to the radiator
