October 26, 200520 yr Hey all...im missing a sensor on my new engine, and i need to know what it is Its a 2.5L SOHC model from a 2000 forester. Its all complete exept for this one sensor...here is a description It is a silver metal roundy block that sits kinda in front of the intake manifold, it has two medium sized vacuum tubes going to it and one electrical wire plugs into it....any ideas??? MAP sensor?? not sure Cory
October 27, 200520 yr Sounds like the evap purge solenoid. EDIT: or EGR control solenoid if so equipped. Trace the vacuum lines, do they go to the backpressure transducer (flying saucer shaped thingy), or do they go to the metal fuel lines that run below the manifold. I am going from memory of EJ22 and Phase I EJ25, so I may be off.
October 27, 200520 yr Author Thanks for the input guys....I agree with Jaime about it being the map sensor....i will get a pic and post so i can be sure
October 28, 200520 yr Sounds like the air assist injector valve, if it is the same as the 01/02. It is controlled by the ECM to allow air to the injectors at low speed to atomize the fuel at a better rate. See if the .pdf below fits your missing sensor:
