starkiller Posted April 7, 2005 Share Posted April 7, 2005 is it possible for these to get "full" or "backed up" or "gummed up"??? seeing as how it deals with the egr and pc solenoid i thought i would look for one of those in a low mileage spi while i was looking for the solenoids....

KStretch55 Posted April 7, 2005 Share Posted April 7, 2005 It shouldn't, unless somehow you've got raw fuel into it. The charcoal just traps fuel vapors, so they won't vent to atmosphere and can be drawn back into the tank and condensed. I think that's how it was explained to me anyway.

Cougar Posted April 7, 2005 Share Posted April 7, 2005 I have heard that overfilling the gas tank can cause liquids to backflow into the canister and damage the filter. Link to comment Share on other sites More sharing options...

starkiller Posted April 8, 2005 Author Share Posted April 8, 2005 just was curious as the canister is much easier to get to then the solenoids are so, are the vapors drawn in at cruising or what? just curious since the light popped on when i pushed the clutch in during 60....

85Sub4WD Posted April 8, 2005 Share Posted April 8, 2005 The vapors are drawn in when the engine is warmed up. - So you would not know of a failure until it had reached operating temp. - I assume you pulled the trouble codes to figure out the EVAP problem - don't bother with the canister - the car cannot tell whether it is or is not working - the only thing that will cause the computer to send a trouble code reguarding that system is the electric purge solenoid Link to comment Share on other sites More sharing options...
