As a 30yr diesel mechanic veteran may I commend you on your video that was easy to understand and well explained.... I’ve been so busy repairing everyone else’s vehicles (been real cold up here in Northern 🇨🇦 -35c the past month) My wife’s 2003 Jeep Liberty light came on the other day and noticed code for both minor/major evap leaks ... Will order all 3 components & extra hosing ..deliverer up here sucks between 1-2weeks if the roads are decent (under 6feet of snow😂) Anyway thanks for saving me time to go look underneath..used that extra time to tune up my SkiDoo😂 Cheers from HudsonBay,Ontario🇨🇦
@@DeathScouter your videos are excellent. My 05 V6 liberty jerks when accelerating and stalls I got codes for cam and crankshaft sensor. Put new ones in and still jerks , engine light is on. I don't drive it much in fear it will cause major damage. I watched your video and changed both sensors myself and rechecked also unhooked battery first for both sensors .??
Well I had no idea you can turn the key 3 times to get a code. Learn something new everyday! Thank you, fixing a 03 Liberty small leak tomorrow. Gas cap wasn’t it so hoses are next!
Just to follow up... my check engine light went off shortly after replacing this hose. Without a "code reader" to erase the codes, Chrysler cars require 40 engine starts (without problems) to self-clear the OBDC codes.
hi deathscouter where is the leading vacuum hose location of the cruise control and heating vacuum switch?....my 2003 liberty has that leading hose inserted in the purge control line in so doing i got a 1494 code..i want to correct that but i dont find where the vacuum line goes...thanks
I just had the same problem. there is also one more section of hose that could be. I know because that's where the problem was with mine. follow the line going towards the front of the vehicle and there is a 6#piece of rubber hose just behind the drivers tire area. real easy to see and change. 5/16 hose.
For the LDP pump, Pull out the passenger side gas tank bolt by the LDP pump and loosen the driver side gas tank bolt. You will have enough room to get the LDP pump out. loosen the two LDP PUMP nuts do not try to take them off. the studs stot into the plastic retainer on the front of the tank. Push the pump up and it will come off. I believe this is on the 2002 model. 2003 and up you dont have to mess with the tank bolts because the pump is mounted lower.
I always search these videos to see anything that might be common across the model. Mine happened to be the lower plastic line on the valve was rotten, just look at it and it was breaking lol
conservatorcivilus That's exactly what needs to be done in my Jeep, but trying to find a place that sells said hoses is a pain in the ass. The hubby is considering buying a length of tubing from an auto part store; possibly 3/8 or 7/16. Any idea's are appreciated! Thanks!
Great Help Sr.I Got code P0455,One of the hose in the canister was split and it was leaking, replace the hose problem fix ones again thankyou for the video Sr....
How much labor could a shop charge to lower the gas tank down and repair the the part above...Shop is charging me over a grand to fix a small EVAP. Leak P0456

Hi Paul, I'm having EVAP problem. Mine started with gas cap light came on, I replaced the gas cap cleared the codes. The next day it started with gascap again. Would you have any tips that could help. I did enjoy the video, thanks for the info.
Wonder if you could help got check engine light on 07 liberty 3.7. was told code is 085 suppose to be 02 sensor right side just in front of the cat. I changed it but still got c/e light. Any ideas ?? thank you
085 is not a full code #, but if you believe you replaced the bad part for that code and the check engine light is STILL on... have no fear. Unless you clear the code with a code reader, Chrysler computers typically leave the Check Engine light on for FOURTY starts of the engine before they clear on their own. Give it a little time.
I have a 2007 Jeep Liberty with a stubborn evap code that won't go away even after replacing the canister and valve next to the battery. I suspect this persistent problem is a pin hole sized tiny leak in one of the hoses. The check engine light comes back on when I initially first start it the following morning when the vehicle has completely cooled overnight.
Even the smallest leak triggers the PCM to create a OBDC code. You may need to let a mechanic do a "smoke test" where a smoke machine pumps smoke into the system and then you look for a smoke leak. If you've already replaced canisters and check valve (and I presume the rubber hoses that they connect with), then you've hit the most likely culprit. Good luck.
After the light went off did the code still appear when doing the 3 key turns? I have a 2003 keep liberty and I think we fixed the problem the light turned off but when I do the 3 key turns it still shows the code
I have a 2006 Jeep Liberty 3.7L code P0441. Slight surging while driving, unsteady rpm's and some sputtering from the rear while idling. Any advice? I'm thinking smoke test and replacing purge valve. Brand new gas cap, spark plugs, air filter, pcv valve, some other stuff.
Should have fixed my evac problem weeks ago but didnt. Now I've git a bigger problem with a P0300 code. Could the evac leak cause that? 2004 Jeep Grand Cherokee, 105,000 miles.
P0300 is a misfire code. I'm inclined to suspect worn spark plugs or 1 or more failing coil packs. Do you get any more P0300-series codes that indicate which cylinder is seeing the misfire? P030X where X is the cylinder #
@@jamespoule8813 You should see my video on changing spark plugs. I can't believe my Liberty even ran with the eroded electrodes I had. MY GUESS would be the spark gap is just at that point where sometimes it fails and sometimes it doesn't. I'm not sure why yours are failing, or why it's been a while since they threw a code, but if you're due for plugs, you might as well change them and swap out the 2 (probably don't need all 6) coil packs for cylinders 2 and 6. It's not hard
+keleidos I just went into my garage, and tried it again. And it works! I must have been turning the key to fast or too slow, this seems to be the trick. My 02' Liberty has since dropped a valve, and needs a new engine. I just bought an 04' Liberty, and will try it out, after I pick it up in a day or two. BTW, the small hose in the video, was cracked, and that fixed my evap leak.
+patsalltheway I've had several people tell me that reading the codes doesn't work on their cars. After checking with the Gods of Google, I'm reading that it SHOULD work on all the Jeep models. After looking at a few websites, there are a few people who say that getting it to work is "touchy" and the rate at which you're cycling the key forward and back makes a difference. I would try again, speeding up or slowing down the cycle. Hopefully that will make a difference. Otherwise you may be stuck taking your car to an autoparts store that puts code readers on for free.
+DeathScouter You are correct! I just tried mine again, turning the key a little slower this time. And indeed it works. And the small short hose, had a crack in it, and fixed my problem. Thank You Sir!
My 03 was working ...now its not reading a code...please help is it bad when no code comes up when you know from the way the vehicle runs something is wrong...Any Suggestions? Thanks in advance
Sorry Thomas. I make videos as I need repairs. In my case, my evap repair was accomplished by finding dry rotted hoses and missing clamps. If I ever need to replace the canister, I'll be sure to make a video.
I didn't know about the key trick. That alone makes this video a thumbs up, for me. Thank you

Actually, I now have to replace the same hose and would have liked to see how you did that. I have the same Jeep. Thanks for posting these videos.
Very informative and well spoken. Thanks for making this video to make life easier for other.
Thank you!! This video was helpful.
Thank you! You explained this very well!
Good video. simple to understand. I will follow up if this fixes my issue which it should. Thanks
I have the same codes, thanks for the tips!!

Where did you buy your part for your Jeep?!!
@@hillary284 For electrical parts and sensors, I only recommend buying from the dealership. All other mechanical parts, any parts store should work.
Thank you , great tips

+tvdigi GREAT! I love hearing back from my viewers. I'm glad you were able to do this yourself.
Where did you buy the hose to replace the middle charcoal cannister hose? One end seems to be wider inner diameter than the opposite end.

Did you ever find out what the unknown part was? Also thank you for the video, it definitely help me get started on my own fix!
Fuel Vapor Leak Detection Pump
What’s the name of the canister next to the fuel tank?

The key trick was begun on Chrysler products in the 1980s, then later shared after Chrysler acquired Jeep.

Could also be a bad seal on a gas cap.

@Trublu Rose Was it the TPS? (throttle position sensor)
@@BenjaminHansen I have no idea. It became undrivable so I gave it back to the dealership it came from and got something else.
Can this be the reason to the ac blowing only from the defroster?
No, you probably had a vacuum leak.
Dang I didt know u can pull codes like that
My 03 liberty has a p1494 code..which states is an e vap leak ... so hope this works....thank you
Jody Churchill Do a visual inspection for dry/cracked hoses. This is the most common cause of evap leaks/codes.
What size hose do I need to replace
I have an 2003 Jeep Liberty and it has the PO442 EVAP system small leak. The question I have is how much did the new cost you?
+Michelle Jones My fix was the hose. I didn't replace any EVAP "parts" per se. My fix was done for just a few bucks.
DeathScouter I have the same codes showing and a split in the same smaller hose but cannot find the exact part. Do you have a part number for it?
What was the symptoms?? Thank you in advance
Usually it’ll run through a full tank in an insanely small amount of time..
Maybe 02 sensors. Two on each side. Upper and lower banks.

vent valve by the way
its a pump and it comes out with 2 -10mm nuts no need to pull the tank.
thanks for the informational. my2006 liberty has code p0049 for evap vaccum. i will share this with my husband and he can check all three areas.
