Jeep Liberty Problem Codes and TSBs



  • jensjeepjensjeep Posts: 3
    hello, i just thought i would put my input in on your issues... you should know you are not alone in this. i have an 02 limited liberty and has done that very thing. hours spent with a computer and different codes or messages reading malfunction. i'm hear to tell you after doing all of the same thing you have done... plug after plug and coil after coil... and still the same crap. grey smoke and flashing engine lights--sputtering and loss of power. after 3 days of trying everything we could think of-- bad gas/ injectors-- ect.. we made then thought we needed to rebuild the engine.. we bought all of the gaskets, rings, oil pump... EXPENSIVE PARTS I MIGHT ADD.

    my husband pulled the engine--- to only find a cylinder head with a huge hole- and one of the arms broke along with the pin. (the sputtering in the motor) (sorry if its not tech terms) oil in places it shouldn't have been. find out very quickly the cylinder heads for the liberty are also costly. :sick: i love my jeep-- i have not paid mine off yet- bought it used and has been the strongest thing i have ever had. bought it with 86k and now has 145k and in parts across the shop. makes me sick but have your jeep checked- before it gets to the point mine did.

    :sick: :lemon: :cry: :mad: omg! all should be mindful of the sputtering and lack of power when your liberty is having issues. flashing engine lights-- grey smoke and the smell of raw gas.

    i know very little about auto parts but am learning very quickly!!! after reading all of these posts its like you all have taken the words out of my mouth! code after code after code--- parts, labor. its nuts!! Jeep/Chry should step up and RECALL!

    we opened my motor- cracked cylinder head. its not coils and plugs and it does not need a gas treatment like all the shops tell you. its your motor! there should be recalls on this issue we all are having. they suck the life and money out of you first. i hope rebuilding the engine will work...i really do love my jeep. i will never buy another one though. if not i'm patching the issue and getting rid of it as fast as i can.

    i'm lucky! my husband is now doing the labor- but the parts are so expensive- this jeep is 8yrs old- we should not be looking at rebuilt motors that cost $2,350.00 or more. a new motor is about $4,500.00. its a shame, because it's a nice vehicle.
  • Thanks for the reply! The dealership said that I had a valve that was sticking and a lot of carbon build up everywhere. I had the valve replaced and all the carbon cleaned off the engine. They said that mine was well on it's way to having the same problem as you listed above. So far, it's driving "normal" since I picked it up from the dealership. I think it's time for me to get rid of the darn thing. I'm not comfortable in it anymore. Good luck with your jeep :confuse:

    so glad your jeep wasn't as bad as mine but i have kept up all the maintenance and is well kept. the engine is clean! oil is gold and nothing is torched. since my last post i have to tell you, not only the issues listed above but found the timing chain tention was plastic and broke into several little pieces. i'm with you, i no longer feel safe or comfortable in the liberty. its a money pit when it goes. i hope the rebuild will fix the problem but again.... i find myself looking for another little 4x4. good luck on a new find! :lemon:

    I have had my Liberty since 2003 (i have 2002 model) and have never had any real problems with it until now. I moved from VA tto South texas in 2008 and live right on the Gulf of Mexico so the car is constantly exposed to salt water. I just had my entire exhaust system replaced as there were holes all up and down the thing from rust. I was so happy to have my car running quietly again. Two days after getting it back, my troubles began. While driving to work (25miles) I stopped at a gas station .5 miles from my destination and noticed a plume of smoke from under the hood. I popped the hood and there was water everywhere from the overflow. I refilled with coolant and went on my way. Obviously I knew this was a problem but had to get to work. On the way home that evening car held temp but had to put the heat on. Being a college student I am poor and drove the car with heat blasting for about a week and a half replacing water when need be (there were no visible leakes so dont know where water is going). Then the overheating became more rapid and I could no longer drive it more than 5 miles without overheating (at speeds over 65 mph) I had thermostat checked and was said to be fine. Water pump is working as it should and oil looks ok with no water intermixed,so I am assuming that rules out the head gaskett. OH, ALSO replaced the radiator cap.. Yesterday had the radiator flushed, and today car was bumping and stalling with engine light blinking. Took it to the shop and guy called and said that there were some misfire codes and that he was going to go back to the thermostat. Could misfire codes go back to a head gaskett problem? Im afraid this guy is going to try and rip me off for when I went in the first thing he told me was the head gaskett was prob dead. before even thinking of any other possibilties. I made it very clear to him that a head gaskett repair was not something I could afford right now and to just run the test and let me know. I just want to know if anyone else has had this happen with the strange slow overheat and stalling problem, let me know what was the deal. Or if you have ever heard anything like this. Even if it wasnt a Jeep. I have read these posts and am now scared that I am in some deep s*it with costly repairs that I cannot afford. This is my only vehicle and has done me good for quite some time. Couldnt have picked a worse time to leave me stranded. Any info will help....

    I have an '03 Liberty Limited 4x4 3.7 liter with 75 k mileage. My check engine light came on & I had it read at O'Reilly for free and the guy said it read "PO 432" or could be "P0432". Anyone know what this is for? He said may be related to oxygen sensor...? He said it would not hurt my Liberty to drive though. What should I do? :confuse:

    Any help & advice is appreciated. Thank you
  • rreidtrreidt Posts: 15
    What is this code? My engine light came on and this is what the guy at O'Reilly said the problem is. He thought it may be related to the oxygen sensor and /or catalytic convertor? What should I do?

    He reset it and light is now off. My Liberty is 4x4 3.7 liter.

    I wonder if anyone can tell me what these codes mean po401 says recirculation flow is insufficient? the other code is po299 says unidentified fuel air metering error? if anyone can help i will appreciate it.

    My check engine light showed up the other day and I took it to my local repair shop where they said a code came up that needed a Chrysler diagnostic to repair so they wrote me down the code to give to Chrysler
    "P1697-EMR (SRI) mileage not stored ? possibly PCM?"

    Does anyone know what that means they weren't sure and I was wondering if this is going to cost me a lot?

    I have been having issues with the car and a friend told me it was a wheel sensor. Sometimes when I brake the brak makes this weird pushing back feeling and makes a slight grinding noise that comes from the brake peddle. I also have an issue that if I go over a bump in the road the wheels quit moving and it take about 20seconds for then to kick on again no matter how many times I keep flooring the gas peddle.

    Is that all separate from the code? HELPPPPP

    wonder if anyone can tell me what these codes are p0401 said exhaust gas recirculation is insufficient? the other is p0299 and it said unidentified and air metering error? when it acts up i get hesitation then it will go but it will blow out black smoke. it will do that then again it will run fine. at appox. 47000 miles i replaced the egr valve wonder if it maybe bad agian. the meter i used was from murry,s parts store it said the egr was ok. any suggestions. thanks
  • What a piece of junk 132,000 miles on it always got the oil changed 3,000 miles check engine light came on driving down the road and it stalls out the odometer needle was going crazy, my husband was out of work trying to get caught up on bills drive it to the chrysler dodge dealer says it needs an oxy sensor, crank sensor cylinder heads and catylitic converter $6,450.00 freaking out do not have the money and mind you the car does not start up
  • Hi there, we had a similar scenario.
    1.) take your jeep to a local mechanic shop, dealers are ripoffs. Have mechanic replace the crank speed sensor located on the right side of the engine block. Hard to see unless its up on the lift. It's threaded into engine block with a 12 volt wire lead that goes back to the onboard computer. This sensor costs about 20 to 25 dollars at a parts store.

    2.)Also have mechanic spray a can of carb cleaner into throttle body intake while engine is running. This will burn out most carbon deposits in throttle bottle and top of cylinder heads. Engine will stall out several times while doing this. Then have him pull the spark plugs if they look carboned up and nasty then replace them at about $4 each, will be cheaper at a place like Autozone. Also it wouldn't hurt to add a bottle of stp gas and carb treatment to the gas tank. Average cost for this job including labor should run about $125- $150.
    Good Luck. Hope this works for you. It did for us.
  • HI i appreciate you writing back I just spoke to them I need $7,400 in parts alone.without the labor They said that I need 2 head cylinders timing belt catalytic converter, that the heads are burnt up. I am so stressed have been crying all day they said something about a speed sensor but never fixed it they replaced the oxy sensor and crank sensor,I owe them 488.00 for that Do you think it will run if I do that, as of right now I need it towed
  • Question for you on this Jeep liberty 2002 that you replace the Piston #2 and works fine.

    Is it still running?

    I have same issue #2 piston. It is sitting on my drive way to either fix or junk.

    please help.

    In spite of what the scan tool says, it smells like a bad EGR valve to me. Questions to pose to you are:

    1. Do you "blow the egr valves nose" on a regular basis, in other words do you with a fully warmed up engine and from s dead stop and with overdrive locked out, stomp on the gas and blow out all of the accumulated carbon from the engine?
    2. Do you do lots of city (stop and go) driving or mostly highway driving?
    3. Are you still using the Mobil 1 0W-40 garbage oil?
    4. Do you clean the boost sensor at the back of the intake manifold on a regular basis?
    5. Do you use any fuel additives or cetane improvers?
  • Hi they say something with piston # 3 I have not done a thing with it yet it is just sitting also, The dodge dealer wanted called back and wanted $7,400 for parts alone for that amount of money It is ridiculous you could get a junkyard engine or parts. I will keep you posted, If you look at post #95 this sounds like something to try before anything,
  • Hi I always use Mobil 1 I also put a gas additive in it, I do a lot of city driving stop and go, I never let the engine warm up and always ran the car with very little gas which was why I went to get the fuel filter fixed and they replaced spark plugs $200 and then had oxy sensor and crank sensor replaced $488.00 and it still will not start. Oh also some times when I did try to start it it sounded like a huge backfire under the hood like a gun shot or backfire but under the hood, I am so frustrated at this point the dealer wants $7,400 for parts alone that is without the labor. I am desperate, Not only that our other car a 1997 jeep wrangler the hose came off and the needle did not show the car was running hot but the car started driving crazy there is oil every where and tapping noise so loud when it did start and that is dead also all of this happened within a week of each other
  • I just read the definition on the EGR valve it is exactly what was happening when it ran the bucking and the shakey idle I will check into this
    Thank you
    I don't know much about cars

    Based on the name you use here, I was under the impression that you drove a Jeep Liberty CRD (diesel),

    First of all your driving habit, mostly city, is contributing to the problems you are having. City driving is the worst thing you can for any engine. Not letting the engine get fully warmed up is bad news too as you will have issues from moisture accumulation as well as carbon buildup in combustion chambers and elsewhere.

    You need to get your Jeep out on the open road and run it fairly hard for a couple of hours to drive out accumulated moisture and to start getting rid of the carbon buildup.

    Looks like you have a mess on your hands. Try someone other than the dealer. A second or third opinion does not hurt. Good Luck!

    Ok Guru's 2006 Liberty 2wd 6 speed 31,900 miles check engine light just came on. Checked the code on the odo. all it says is 6.3 before it displays 0.0 for trip miles. Jeep has been a great car. Only problem to date has been L/R window, but found a metal part on line and was an easy fix. I have been recently getting a noise in the R/R wheel when braking so I'm thinking new pads. other than that has been fine. 6.3 for a code seems strange, any thoughts on this?
