    I have checked the bulb, and the horn comes on when I hit the lock button, but I still can't seem to arm it. I bought it from a Dodge dealer and they used it as a certacy vehicle.

My 2001 town and country mini vans check engine light won't go out. It was tested at auto zone for a gas cap problem. I bought a new gas cap and drove over 50 miles now and the light is still on.

    My 01 caravan has same problem. Key dance showed 0455 and 0442. DIY smoke test (idea from youtube) had smoke pouring out around gas cap. Replaced gas cap, smoke retest showed leak in filler neck:( So much for my $89 savings for a smoke test!

You need to have a smoke test done to see exactly where the leak is. The cost should be aroung eighty dollars. I am sure the leak is in the fuel filler neck.

I had the same problem, tried the gas cap, didn't work. Have someone check your filler neck had a rust hole, that was my problem. I had a hard time finding one used and in good shape here in NS. It is very common around here.

Is your gas cap tight? check it, these codes indicate a large leak in the fuel evaporative emission recovery system at the gas tank

Check engine light stays on


There could be many reasons your check engine light turns on. The light means that the computer in the vehicle detected a fault or problem with a part or system such as when low air flow is noticed. You can buy a code reader at a local parts store that will tell you what the codes mean, or some vehicles can tell you what code it is using a flashing light much like Morse code.

I just bought a 2006 dodge grand caravan with 66,000 miles on it and the check-engine light came on!!! It seems to still drive fine but I am not sure what this is caused from!!!


Take it to Advance Auto Parts, or Auto Zone, they will scan your computer for free to get the code and tell you what it means. May just be a sensor, or the gas cap isn't tight (emissions) may or may not be serious. Thanks.

I can't find the thermostat on my 2001 Dodge Caravan. Can someone help?


Hello jhenry246, my name is JShreader. Thank you for choosing fixya.com

The Thermostat is located behind the Thermostat Housing on almost all Vehicles. There are 3 different Engine types they used in this Caravan this particular year. I have uploaded you pictures showing the locations of the Thermostat and Housings for each Engine in .pdf format. You can download them by clicking HERE. The engine cooling thermostats are a wax pellet driven, reverse poppet choke type. If you follow the Upper Radiator Hose up to the side of the Engine, it connects to the Thermostat Housing.

You must drain the Cooling System before you remove it. I went ahead and made you up the replacement procedures for replacing this Thermostat. You can download it by clicking HERE.

I hope this helps you. If you have any more questions or need any more diagrams, please don't hesitate to ask...Thanks again, JShreader!

Yellow engine light(IDK)?


the yellow light is the check engine light, the best thing you can do is find someone who has a hand held code reader and let him come to your house. it will pull the code on the engine and tell you exactly whats wrong.
