I am getting a PO1420 on my OBD2 reader, I have contacted the dealer they tell me this is a Fuel Tank Pressure control Solenoid Valve. Does anyone have a idea of the location of this valve?

1997 Outback with 160000km

You didn't state model / year, but they are all in the same general area on 99 and newer. Rear underneath by the Charcoal Canister. Attached .pdf should give you and idea of which one and what it looks like.

So the sensor and the controller are the same? Thanks for the printout. Are you able to access the sensor from the top ports?

 

Thanks again

P1420 says the ECU (Electronic or Emissions Control Unit) has detected a short in the Pressure Control Solenoid. It still has +12v on the ECU pin after the ECU tried to 'ground' (activate) the pressure solenoid. This is an electrical failure, maybe a shorted coil on the control valve, not a failure of the valve to open. That would be another DTC.

 

Likewise it's not an open or bad connection, as that should set another DTC P1400....Vent Valve Low.

 

I would unplug the valve and check it's resistance. The manual states 10-100 ohms. Less than 10 ohm on the coil of the valve sets this code.

 

Good hunting !!!
