Got a P0446 code. Cleaned out the purge vent near the tank...It worked for a few weeks. Then I didn't hear the clicking after driving for a few miles. Thought the valve died. Replaced it and still don't hear it clicking.
I think the problem may be the fuel tank pressure sensor. Anybody know what the resistance should be in the sensor?
See if you can get your hands on a cheap scan tool and see what the fuel tank pressure sensor data is. Remove the gas cap and see if the pressure changes, if not, blockage or faulty sensor. Youre not setting any control circuit DTC's for the sensor, so I suspect wiring is okay at this point.
Tank sensor installed. Drove it around, and didn't hear the purge solenoid click, but maybe the code has to be cleared first. Did that tonight. Will drive tomorrow. I guess I check to see if the new purge solenoid is actually good.
