  • Have the above code on my 2001 Dodge Grande Caravan. Looking it up it says: leak detection pump switch or mechanical fault. What is this? Where is this pump located? Thanks for any help!

    I have a 2002 Dodge Caravan which had a code 455 and 442. The following is a description of this van. The problem was caused by a 12 inch hose located under the van on the drivers side close to and in front of the liquid/vapor separator canisters. The 5/8 inch ID hose was connected between the front (engine side) of the LDP vent valve and the leak detection pump. Oil from the engine had leaked onto the end of hose connected to the pump. The plastic clamp was broken and the hose had swollen until it was very loose. Replacing the hose and clamps fixed the problem. The LDP vent valve is connected to the largest liquid/vapor canister by a 2 inch long hose. You may need to buy the hose from the Chrysler since it is a shaped hose. Any broken or missing clamps should be replaced with the band type sold by auto parts stores. Any other hose which is split should be replaced. I found one small L shaped hose with different IDs on each end connected to the small liquid/vapor canister which had a small split which I replaced with a hose I got from Chrysler for $5.
  • It is raining in my car! I cleaned out the drainage tubes which were totally plugged and thought that would solve the problem. (I live in Portland where it rains constantly). The passenger side drain tube is cracked at the bottom but before I replace that I'd be thrilled to hear some advice. I finally had a dry 3 days and the car seemed fine, so I ran a hose on the windshield, the passenger door, basically all over the front end of the car. Nothing. As soon as it started to rain again, there's now a slow stream of water coming out from underneath the glove box. It smells like water, has no color. It did disappear when I ran the heat (which I haven't done in months), but then slowly trickled again. This can't be normal?! I really want to sell my car but want to identify and fix the problem so I don't pass it off to a buyer (but obviously don't want to break my bank in doing so). Please help!!!
  • I recently fixed up this van for my handicapped friend. (Auto,since only 1 leg.) While driving the other day, it suddenly lost power to the accelerator. Still running though, for about a mile, and then suddenly had accelerator again. Your help to correct this is appreciated. Need to keep my friend in wheels.
  • Car-part.com will search all the U.S salvage yards and give you a # and price!! Most will ship you the part you need
  • Had the same problem took forever to find where the whinning was coming from. Look under the middle of the car while running and listen for a whine while someone else eccelrates it. There is a plastic 3 ball looking thing that has a vacumm in it that helps with pressure. Mine was shrunken from heat and therefore leaked its called a Vac Harness and it was 8.00 from the dealer. part # was 4431325 hope this helps good luck.
  • I bought a 1996 grand voyager three years ago........ just yesterday I tried to detach the spare tire from under the car and I can't figure out how to do it, can't find in the manual how take it down, can somebody tell me how? It seems nobody has ever taken that tire off.
  • You have to lift the tailgate and make sure nothing is in the back. You should have a part of the rug that has a plastic round piece in it (driver's side of the compartment.) Lift it up and you should see a white plastic lug that you jack wrench shoud work on. turn it counter clockwise to lower the spare tire all the way down. Do you know where your jack is kept for you van?
  • I'm having the same problem, did you ever fix yours and if so, what did you do?
  • I cleaned the mass air flow as instructed to do by the source I gave. It helped some but still has some problem but not as bad as before.

    The problem that I'm having with this thread is that, as far as I know, no 3.3 or 3.8 liter engine produced by Chrysler for use in their minivans has ever had a MAF sensor. Instead, these engines use a Manifold Absolute Pressure (MAP) sensor, a sensor that shouldn't be messed with. If someone attempted to clean a MAF sensor on one of these vehicles, there is a good chance that they will irreparably damage the MAP sensor.
  • I have a 2005 Dodge Grand Caravan, 3.3 L and I think the oil pump is going out. Can anyone tell me if that procedure can be done just by removing the oil pan or will the motor have to be removed? Thanks.

    What makes you think the oil pump is failing? I ask because that would be a VERY unusual failure for your eninge.
  • When I start the motor for the first time in the day, the oil light will come on and stay on. I don't know exactly how long it will stay on because I've only let it run at the most 2 minutes before shutting it off. The engine sounds good during that time. So, my routine is, start the car, shut it off, start it right back up. The light goes off normally after the 2nd start. This only happens once per day. I change the oil & filter on a regular schedule and I maintain the correct level. I changed the oil 2 days ago and for the first time when I started the van to check for leaks, I heard a noise that is similar to valve train ticking with low oil. That only lasted about 3-4 seconds. My guess it is the oil pump even though the ticking hasn't returned.

    A few points:

    1) While the oil pumps have proven to be extremely reliable on these engines (as have the engines themselves), the oil pressure sending unit shows up as an occasional problem area. The standard operating procedure for debugging this is to A) remove the oil pressure sender and screw in a physical gauge, and B) assuming the gauge shows the oil pressure to be in the normal operating range, replace the sender.

    2) A little lifter noise following an oil change is normal for ALL cars and ALL engines, especially so if you don't "prime" the new filter by prefilling it with oil. These engines are also picky about the quality of the "Anti-Drainback Valve" built into the filter, and following a cold-start on some engines using a filter with a less effective ADV will cause the same valve train noise you heard following your oil change. FWIW, I've found that the Motorcraft FL-1A oil filter keeps my engines very quiet following a cold-start, that said, the FL-1A is a larger capacity filter and will require you to add say 5.25 quarts of oil following an oil change to bring the oil level up to the MAX line on the dipstick.

    Long story short, have your engine tested to confirm that the oil pressure is acceptable, and if your engine is like 99% of the other ones out there with an oil pressure light issue, simply replace the sending unit.

    Best regards,

  • I had this problem too. Thanks for your solution
  • If you would check out Auto Advantage site,(http://corp.advanceautoparts.com/english/youcan/knowhow.asp) they have tutorial videos that talk about cleaning this MAP/MAF sensors and show where they are located. I have a MAP on my 2003 van and a MAF on my 1993 Plymouth Acclaim. I cleaned them both as instructed to do. http://videos.streetfire.net/video/How-to-clean-your-MAF_80603.htm

    Back to my point, no 3.3 or 3.8 liter engine has ever been manufactured with a MAF sensor. As for cleaning a MAP sensor, not worth the effort. Why? Ninty-nine times out of one-hundred, when a MAP sensor has a problem, no amount of cleaning will even remotely help, the sensor needs to be replaced. If the sensor isn't having a problem, then cleaning it will not improve engine performance in any way, shape or form.
  • My 2000 Chrysler Voyager just stops as I am driving. It will continue to stop 10 to 15 times, and then it can be perfect for the next few hours. We changed the crank sensor but it still doing it.

    Hot / cold weather, full or empty tank it doesnt matter.

    Any ideas????
  • How about the fuel filter? Mine is a 1999, so I am not sure that the 2000's have a filter. Mine is under the car and costs about $35 from Advance. There are different filters for the Grand and short wheelbase models. Intermittent problems are very difficult to diagnose.
