Ok.. So one day my CEL came on, I only have 26k on my 2010 WRX sedan.
Used my OBD2 bluetooth adapter and the android torque app to see it was a P1400 code.
P1400 - Fuel Tank Pressure control solenoid valve circuit low
So I took it to the dealer. They checked it out, they found what was a mouse nest under the rear seat, They wanted me to bring the car back so they could further investigate.
So me being me, I brought the car home, pulled the back seat, and investigated the wires they had said were chewed on by a mouse.
The mouse or mice nibbled on a few wires, not even cutting any. only one had some exposed wire.
So I taped them up and tried clearing the code.
the code cleared but came back in later.
I don't think that these "chewed" wires are really the root of the problem. Has anyone else had a p1400 CEL code?
The wire that was chewed on has a part number 81578FG410.
it runs the whole length of the car on the passenger side. but the 7 wires that were in the bundled that were chew on go to a white box under the vapor canister on the passengers side behind the back seat.
