Town & Country/Grand Caravan Problem Codes

What does this mean? Exhaust Gas Recirculation Circuit Malfunction. Cod PO403


  • I have a 00' town and country minivan. my engine light came on today, and I got it checked out. Its a leak in the emission tube and needs to be fixed. They said I needed the length of the pipe to fix it, but I don't know which one it is. I was wondering if there was anyone out there that knows where it is. and/or knows what size it is. I have a 00' town and country mini van with 3.3l engine. 2wd.

    You have to be more specific. What trouble code is the check engine lite on for? There is no such thing as a "emmission tube"
  • My emissions light is on and was told I had a small leak in the evap line.
    I have codes P 0442 and P 0456 Can anyone tell me what they mean? Thanks, Jack

    Both of these codes indicate small leaks in the evap system. Could be a problem with your gas cap. Could be it wasn't tightened well after fueling? Or it may need to be replaced with a new cap. Also, check the evap system for cuts and/or holes in lines/hoses.

  • I have a 96 Dodge Grand Caravan 3.3L V6 w/ 140K miles. Engine suddenly began running rough, check engine light came on, and vehicle stalled after another minute or so. Mechanic replaced Cam Sensor and Ignition Coil. Vehicle started up and ran fine for about five miles and then same thing happened. Based on code 351, Ignition Coil again replaced and vehicle again started and ran fine for about five miles before happening a third time. Code again shows 351. What is causing this?

    I have a similar problem with a 97 3.8 Town and Country: The car occasionally misses/loses power. Sometimes it won't start. I replaced a bad gas cap after an evap error. a few days later same old thing. Then a cam shaft sensor error occured. Replaced that. I put a test light on the coil pack connector from computer. When it won't start, it will only fire the plugs for the first 3 revs or so. The ASD relay is remaining on as it should.

    If your van is a 96 (or later), then it should have the OBD-II system. The easiest way to read the diagnostic codes is with an OBD-II scan tool. Lots of companies make them. You should be able to buy a basic one (capable of reading and clearing codes) for under $50. You plug it into the OBD-II port (a connector usually located under the dash someplace), turn the key on (but do not start the engine), and it reads and displays any codes.

    I don't know about your '96 T&C, but I had a '96 Cadillac Deville that would display the codes on the instrument cluster after some ignition key and/or instrument panel push button sequence. Your T&C probably can do the same thing, but I do not know the magical sequence to make that happen.

    Buy a cheap scanner. You can use it on any 1996 or later vehicle.

    Some auto parts stores will read the codes for you free of charge. I think Auto Zone is one of them, but have never used them myself.

    If you have an owner's manual you can find the location for the power mirror fuse in it. Most likely it's under the dash on the driver's side with a cluster of others.

    Why did your mechanic say that your fuel system needs to be serviced? Is he talking about just replacing the fuel filter or something else? Is he saying this just because of the miles? If he's talking about a fuel injector cleaning you can probably get good results yourself if you buy a bottle of a QUALITY injector cleaner at an auto parts store and add it to the fuel tank. Pay attention to the recommended ratio of gas to cleaner on the label before you just pour in an entire bottle.

    Replacing the EGR valve can be done by a home mechanic but it's sometimes not all that easy to do, especially if exhaust heat has made the fasteners nearly impossible to loosen. You can purchase a new EGR valve at an auto parts store but be sure you have someone lined up to do the work who is willing to crawl under the vehicle and get his/her hands dirty.

    The fuse box is under the hood.But it doesnot have the fuse for power mirrors.Someone said that it is with the power mirror control switch.How do I take the switch from the dash.
    ref. fuel system service; My engine light came up and i went to a shop to decode it and there the mechanic said that i must replace the egr switch and fuel service.I dont know what he means by fuel service.the code was P0401.
    I am willing to go under the engine and try to replace the egr switch.Where is it located on this car.
    Tons of thanks for your help.
    I am grateful

    The fuse box is under the hood.

    There should be a second fuse box under the instrument panel on the driver's side. Look on the inside of the cover for anything related to the power mirrors.

    On the EGR valve, if you see a pic of what one looks like it shouldn't be too hard to locate under the hood. Although they are replaced from above, sometimes you have to get underneath to loosen the large tube that goes to the exhaust. That's the one that can give you fits from the exhaust heat over the years making it nearly impossible to remove. I've screwed up some of those tubes trying to wrench those things loose before.

    Here are some links that might help:

    EGR Valve Testing

    EGR Valve Replacing

    Replacement EGR Valve for 2001 Grand Caravan 3.3L

    You might be able to get by with just cleaning out any carbon and crud (for lack of a better word at 2:00 a.m.) from the EGR valve and intake manifold ports that it bolts onto. You'll see what I mean after you remove the old valve. I've used Berryman's B12 intake cleaner and wire pipe cleaners in the ports to loosen and remove deposits in the past.

    Also, carefully check any vacuum hoses related to the EGR for holes, damage or looseness. I would think that the mechanic would have already done this.

    BTW, that P0401 code is an Exhaust Gas Recirculation - Insufficient Flow fault.

    My 2001 Town & Country LXi (3.8L) has recently needed the Radiator fan replaced (broken fan blades). When I cleared the trouble code for the fan I found that there were three other codes P0003 Fuel Volume Regulator Control Circuit Low and P0200 Injector Circuit along with P3FE0 - Check service notebook.

    Any insight on what this means? Where to I start to diagnose the problem? I've checked the web, but haven't found anything that was more than "you have an injector problem"

    came on, I did the on off on off thing to get code and it came
    up P0406. Found online that this means Exhaust Gas Recirculation sensor A circuit High. I have know idea what this means. Could anyone explain this and is it costly to fix.

    i had the exact same problem on my 2001 GC. after reading several posts this morning, i took the lower half of my dash apart, removed the mirror switch, etc. don't waste your time. the fuse is located in the main fuse box under the hood on the drivers side. the fuse is marked "A/C clutch". (??????) i had removed the fuse when the clutch on my a/c compressor went, why the mirrors share that fuse i will never guess. if your a/c clutch is bad and blowing the fuse, you can try what i did, i pulled the a/c relay below the fuse. i hope this solves one of your problems.
  • most likely it is not the cap, it is the filler tube, and you can get it from the dealer for $75
  • How do I bring up the diagnostic codes for a 2005 Chrysler Town & Country doing it myself?

    My 2001 T&C LX has the ABS light and the Brake light on. I had it scanned and the mechanic said the code was unknown to him. It had something to do with a valve issue (?). I checked the relays and all we OK. What next?
  • We can't really tell you much if you do not give us the code numbers.
  • I have a 2004 Chrysler Town and Country Van. The check engine light is on, and the diagnostic code P0032 is coming up. What does this mean?
