10/89 Subaru Legacy EJ22. NA. Multiport Fuel Injection.
Throwing...
Code 45: Pressure duty solenoid (turbo)/atmospheric pressure sensor circuit (non-turbo)
Where is this thing located?
I have 2 guesses but want to make sure... Guess 1) Passenger side underneath the intake between the manifold tubes there is a square looking thing with 2 vacuum lines and a connector.. Guess 2) Between the air filter and the intake, has the single multi pin connector.
Update: Pictures on the internet seem to think this is sitting right in front of the strut on the passenger side. I have nothing there...
Update2: "The atmospheric pressure sensor is located inside the ECU", don't know if this is true or not.
Thanks for any help!
