I am getting a P0446 code on my 1996 Explorer V8. I have reset the code now about three times and each time it has returned. I also made sure my gas cap was tight and clean, and I am still getting the code. There is obviously a problem somewhere. Where is the charcoal canister located on these? Any suggestions?
Thanks.
Just an FYI PO446 = Evaporative Emission Control Canister Vent (CV) Solenoid Control Malfunction
Possible causes
VREF circuit to FTP sensor open
Damaged FTP sensor
Carbon Canister Vent Restriction
Kinks or blockage in the fuel vapor host/tube between CV solenoid and atmosphere
CV SIG circuit short to PWR GND
Damaged CV soleniod
Damaged PCM
