P0446 CODE

1999 Geo Prizm

Computer problem
1999 Geo Prizm 4 cyl Front Wheel Drive Automatic 65000. Miles

Hi. I have a 1999 prizm that keeps popping a p0446 code. I've seen a number of possible reasons with no clear way to start figuring this thing out. Any help? Thanks, rick

First check the gas cap and make sure it is on tight and sealing properly. Take it to any auto parts store and have the code erased.
If it comes back then there is a vacuum leak, or solenoid problem in the EVAP system.
