Discuss the causes and fixes for P0447 2012 Nissan Altima Sedan OBDII Code
-
2012 Nissan Altima SR 3.5L. Had P0101MAF code and cleaned the MAF sensor which made it go away.
Then had a P0442 Evap Emission System small leak code so changed the Intermotor Canister Vent Solenoid.
We are now getting a P0447 Vent Control Valve and P0442 Evap Small leak.
Any help would be appreciated. -
The P0442 and P0447 codes are not related to the MAF.
Since you have both codes, I recommend starting by double checking the Canister Vent Control Valve hoses, but if the hoses are OK then you may have to replace the Canister Vent Control Valve.
