Default 04/05 STI swaps P1446 Code HELP!

So I have removed all the codes except for the "Fuel tank sensor control
valve" code P1446. This is because this extra valve isn't on the RS tank, and well, obviously the ECU is looking for it.

QUESTION: Does anyone of the resistance of this sensor? If anyone has one lying around, can you check too see how many ohms this sensor has.


I can't find one anywhere to measure myself, and i don't know anyone who will help me flash it out free, and i need to smog my car by the end of the month.


Any help would be appreciated.

all that is required is that the ecu 'see' 12 volts on the wire going to the vsv. use a 1200 ohm 1/2 watt resistor, connect one end to any ig power and the other to the ecu pin used on your application.

ok, but the 'heat' is calculated at .144 watts, you cannot even feel it.
