02 f150 P0443 need help
I have an 02 F150 engine light came on showing P0443. I have checked to make sure the evap can has 12V and it ohm reading is 33 across the terminals. I don't know where to go from here.

Ok sorry it has been a long road. I have the problem fixed
. I checked every hose, took the bed off and checked all EVAP components with ohm meter, checked wiring for shorts or opens. Then made sure I was getting 12V to Vapor canister vent and purge solenoid when key on. Changed connector to make sure it had good connection. Everything checked out good so I looked at PCM and ordered a new one and sure enough after replacing it no check engine light. Had new keys programmed after PCM installation. I had to drive it 257 miles before all systems were reporting, but finally got it inspected.
