tjxtreme Posted April 20, 2006 Share Posted April 20, 2006 Hello, I was reading in the Haynes manual about a relay (i think) for a hose leaving the cannister. I am having some light fuel vapors enter the cabin and want to test it. Where is this located? Also, I recently replaced my fuel filter. following the haynes manual, I depressurized the system by disconnecting the fuel sending unit and running the engine. there was no fuel pressure to begin with (ie when i started it to run the fuel out of the lines, it never even started). Is this cause for concern? I have checked the lines for leaks thinking that a crack in a line would lower fuel pressure and allow vapors to enter the cabin, but may have missed some parts of the line (i was only able to find them near the tank and in the engine compartment). Thank, Andrew Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted April 20, 2006 Share Posted April 20, 2006 There's a canister purge solenoid under the passenger side intake manifold. It's the thing with the blue electrical connector http://www.main.experiencetherave.com:8080/subaru/images/injectors/DCP_2471.JPG BTW, post what year & model vehicle you're referring to.

tjxtreme Posted April 20, 2006 Author Share Posted April 20, 2006 sorry- its a 99 2.5L outback wagon. does this still apply or is it in the rear nearer the cannister? Thanks, Andrew Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted April 20, 2006 Share Posted April 20, 2006 On the newer cars, the charcoil canister is in the rear of the vehicle. The solenoid should be in the same spot as previous models. Quote Link to comment Share on other sites More sharing options...
tjxtreme Posted April 21, 2006 Author Share Posted April 21, 2006 Thanks, I found it. I couldn't get the leads in to check the solenoid resistance (but I will once I have time to move some stuff and get more room to work with back there), but the voltage to the solenoid read 2.5 mV. Is this appropriate? It seems low. Thanks, Andrew Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted April 22, 2006 Share Posted April 22, 2006 When were you checking the voltage, was the engine running, and were you checking the voltage on the wiring harness side, or sensor side? The solenoid is only energized, ie seeing 12 v under normal cruise. Quote Link to comment Share on other sites More sharing options...
tjxtreme Posted April 22, 2006 Author Share Posted April 22, 2006 I was checking the wiring harness with the key in the 'on' position, but engine off, according to the haynes manual. I'll give it a try with the engine on. Also, I cant get the test leads into the solenoid. Do you recommend unbolting the solenoid or removing the offending hoses to gain access? Thanks, Andrew Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted April 25, 2006 Share Posted April 25, 2006 Yeah, I'd remove the solenoid if you can't test the leads with it bolted to the manifold. Quote Link to comment Share on other sites More sharing options...
