So im getting evap codes on my jeep. So far i have replaced the gas cap (OEM) and the evap purge selonoid. The codes kept coming back took it to get smoke tested and the only place it smoked was the LDP filter (black cylinder by the charcoal canister ). Im not sure if that means the LDP needs replaced or not im not throwing any LDP codes (if those are real things):atomic:

I will pull it and see if it needs cleaned out. I wouldn't be overly concerned except PA emissions. Hopefully a cleaning will help as a new one is 110 and im already 200 deep in this fix.

Def will and yeah 200 from the dealer prolly for one...rock auto has one for 110 i believe

So pulled it lut amd its clean as a whistle...but it appears the previous owner may have tried that already as the top part near the clips had broken chunks in the plastic...might be time for a new one...

2001 tj 4.0...i had it smoke tested i assume a cracked hose would have leaked smoke only thing that leaked was the LDP filter

 

[KilzZombies]

I think they tried to jump the vent valve and said the couldn't get it to close but they told me it was the purge solenoid which i jumped myself and heard it working...so maybe he meaty he couldn't get the LDP to close properly and called it the wrong thing

 

[KilzZombies]

So unplug purge solenoid and run engine with LDP still plugged in or do i need to apply current myself? Then smoke test

To update all I took the jeep to get it retested and asked if they had properly done the LDP. They retested it for free for me and found that the motor wasn't working properly on the pump. It would click off and on. So they then manually closed the hose off to finish the test. And there is a leake "somewhere near the gas tank" i asked if they could be more specific and they said without dropping the tank it was to hard to tell. They suggested 3 lines that run to the tank or the O-ring for the fuel pump be checked....at least we now have some direction here...

The electric solenoid is what was clicking. That is my fault for using incorrect terminology. They hooked it to a battery and i could hear it clicking and then a good one so i could hear how it stayed on. I am starting at the rear though to see what is leaking back there

I ended up replacing all the rubber lines to the tank to fix the rear leak as I threw a different code after I replaced the LDP. All in all I'm finally inspected after lots of emissions headaches left for my by a previous owner. Thanks everyone for the assistance.
