86subaru Posted April 6, 2008 Author Share Posted April 6, 2008 update, both hoses go to another gray sensor, thinking is might be bad, what is this sensor called ,thanks Quote Link to comment Share on other sites More sharing options...
EVOthis Posted April 6, 2008 Share Posted April 6, 2008 if you are refering to the one mounted right below the MAP sensor and a little to the right(on the shock tower) i think its called the pressure exchange solenoid......i asked a question a while ago about it.....the best answer i got was that the function of this "solenoid" was that it switched between atmospheric and manifold pressure for some reason or another......im sure theres threads out there about it.... i havent had a chance to look it up though.....

86subaru Posted April 6, 2008 Author Share Posted April 6, 2008 no, if you follow the hose past the tps and towards the front of the motor , it connects to a gray sensor, and a plug , could this sensor be bad, ? causing my barometic pressure switch [ map ] code, but thanks Quote Link to comment Share on other sites More sharing options...

EVOthis Posted April 7, 2008 Share Posted April 7, 2008 i did see the sensor you were talking about.....i have no idea what it is....it could be the ECT but why on earth would they run manifold vacuum to that..........again im surprised no one else has chimed in......i cant even find that sensor in the haynes manual i have.......
