January 1, 201313 yr 99 Impreza Outback Sport. So, I pulled the codes this morning and got a 420 Fuel Tank Pressure Control Solenoid High Input and 440 Fuel Tank Pressure Control Solenoid Low Input Where are the above? Thanks, UMT
January 1, 201313 yr Author Ooops, looks like you gents are correct. Is there a quick fix? Thanks, UMT
January 1, 201313 yr The P0440 is an evap code and usually it leads to a rusted through fuel filler neck. Is fairly easy to check, just need to remove the right rear wheel and there is an access panel behind the wheel.
January 1, 201313 yr 420 often solved, atleast tempoarily with seafoam through vacuum line and/or spark plug non-fouler(s). Search around here a bit to see how to do these.
January 2, 201313 yr P0420 catalyst efficiency below threshold. P0440 evap emissions system. You got the wrong codes. Your definitions are for codes P1400 and P1420. The pressure control solenoid valve is located above the charcoal canister behind the right rear wheel. All of the metal parts back there are prone to rusting. I don't envy you having to remove the canister to get to that valve. I'd expect some corrosion in the wiring or inside the connector. Good possibility of mouse damage too.
