palfer Posted August 2, 2020 Share Posted August 2, 2020 Hi My 97' Impreza just came up with a P1441(fuel tank pressure control-high input). I'm assuming that means the pressure is too high and the system can't relieve it. I connected the green connectors under the dash and was able to verify the purge control solenoid (under the intake manifold) and the vent control solenoid (above the charcoal canister) are both turning on/off. However the pressure control sensor (mounted to body on passenger side of hatchback behind the apron) is NOT giving any audible click or pulses. What I'm not sure of is if the pressure sensor is supposed to pulse when the green connector are joined. Any ideas? If not, does anyone know how to test if this is working? I also looked over my fuel filler neck and its got some rust. I don't see any pinholes but I'm thinking if there were that would trigger a P0440 for an evap lead which I am not getting at this time. Thanks! Quote Link to comment Share on other sites More sharing options...
