Hi I have a common issue that I'd like to start fixing on my own. The Malfunction indicator light comes on every year on my 2005 Jeep Wrangler. I believe that the gas gums up something. I heard that all you need to do is clean out something with a toothpick, but I don't know what or where it is. Thanks, Doug

    Hi, can you tell us the trouble code?

  • dougluers Jul 02, 2011

    Thanks for the quick reply--New at this--don't know how.

    Do I need to hook it up to a computer or go to a place like autozone to get the error codes?

    The indicator is not flashing and performance has decreased since the light came on. It surges forward upon stopping, which I've paid a mechanic to fix before. He's the one that said it's just the additives in the fuel build up on something and you can clean it out.

    thanks

    Malfunction light tells you there is a problem, but not where it is. You need to have the system scanned to find that out. (most larger parts stores do that free). The problem you have now may or not be related to the one you had last year. Compare what the scan code tells you to what your previous repair bill said. Then ask again so someone can help. Been doing this a long time and have no idea what you can clean with a toothpick!!!

SOURCE: 1998 Jeep Wrangler TJ Headlights working intermittently

I have a 97 TJ and the headlights wouldn't come on but the parking lights would. Funny thing was that if I pulled the brights to flash someone, the brights would work. I took out the old headlight switch ($26 at Checker) and they work again. When I pulled the switch there was one connector that seemed to be corroded. Hope this helps

SOURCE: jeep 2008 patriot esp light on Malfunction

Check under drivers door sill step. There is a spice I believe the wires are red or pink in color. The splice will be wrapped in black hockey tape looking stuff. Peel the the hockey tape stuff off and you will find that this splice is corroded and not making contact anymore. You can repair this splice and your problems will be fixed. Be sure to use some good heat shrink on your repair to prevent from happening again.

SOURCE: 2005 Jeep Wrangler Unlimited cruise control will not engage.

check the vacuum line on the right side of the engine. There should be an elbow connector connecting the line to the engine. Does interior fan only come out of the defroster vents by chance?

My 2002 jeep wrangler isnt idling right , stalls , hesitation and barely reves. its throwing p0201 , p0202 , p0352 and p0353. the injectors arent bad and im getting a good spark from coil rail ports.

Is this a 4.0 liter or a 2.5 liter wrangler? Sometimes the crankshaft sensor causes these things to make these codes come up. Crankshaft position sensors are very common of going bad on Jeep vehicles.

My malfunction indicator light came on and won't go off

Read your owners manual

Why would a Malfunction Lamp come on,
& then go off, if you don't diagnose the problem
& make the required repair.

That technology is 30 years old & your not
up to speed?

Most likely a small evaporative leak will be from the gas cap. Replace the cap, then leave your battery unhooked for about a half hour to clear the code.

Engine keeps missing. unknown codes

Code 1682 indicates low battery voltage. This could be a problematic alternator, which would likely cause misfiring. Autozone should be able to check this for you for free.

Code 1391 indicates the computer can not see the crank or cam sensor signal. This would likely be a result of the misfires.

Code 0320 indicates the crankshaft position sensor reference signal could not be found while the engine is cranking.

All of these issues point to either a cam/crank sensor malfunction or a charging system problem, either or both of which could cause the misfiring.
