it seems to always happen after i get gas, about 25mi to be somewhat exact today it happened when i was @ about 70mi. also on two occasions the check engine light goes off w/o me disconnecting the battery, kind of odd no ?
|08-18-2011 09:56 PM|
cleared the code
just by as i suspected (see previous post) disconnecting the + cable from the battery for +2 minutes.

well, it happened again and i'm pretty sure it happened at around the same milage after filling up the tank (FWIW) anyway. is there a way (short of spending 100s of dollars and/or taking it to the shop) to reset the Check Engine light, i was searching Napa and AutoZone's web sites but even though i've been here in the US 11 years i do not always know the right search term since English is not my native language
added: is it really as simple as disconnection the battery for a bit ? found that here.

It will probably happen again, but if it only the sending unit and not the pump it won't hurt anything to keep driving it unless it just annoys you to the point you can't stand it. When you can't fix it by cycling the key anymore is when I would get it fixed. Even if the gauge is reading correctly, the MIL will stay on until the PCM decides it was a false alarm. It's usually 3 drive cycles, but I'm not sure if that's what Chrysler does or not.
FWIW, at the shop I worked at it cost a ton to do a fuel pump on most Jeeps or trucks that looked like they had been run offroad. They accumulate a mountain of crud on top of the fuel tank that has to be cleaned off once the tank is out so it doesn't get inside the tank when the pump is removed. Depending on how bad it is, it could add an hour to the job. You can't expect the shop to clean up the mess you made for free.

weekends are too short

|Eaglektd||Anytime rudeboy, glad I could help out. I hope that the code doesn't pop on again, but I would expect it to happen down the road at some point so just be ready. Enjoy your weekend sir.|

i understand they are "in it" for the money.. but frankly to me it sounded like a rip-off. in any event, shop diagnosed it what we already knew, fuel level sending module (as he called it), it's intermittently -he cleared the check engine light and said keep driving until it possibly happens again.
everything pretty much as Eaglektd said, he was a great help!

|Eaglektd||Keep us updated. Anything dealing with fuel tank repair gets expensive at the dealership, when I was a service advisor there I would charge 2 hours labor minimum to take down a fuel tank and 3 hours if it was full cause they get heavy and that makes everything harder not including the actual repair. Part of the problem is how they pay service advisors, I was paid only commission and my hourly labor rate is what that was based on, so doing oil changes or other small things without at least 2 hours weren't even worth my time, it is a racket.|

well... took it to the shop, called dealer i bought it from and he said it's extended manufactures warrantee. so i called a Jeep dealer who told me that the fuel pump is not covered under power train warrantee. so i ask the shop guy (i already know the part is ~$230 online) how much is the repair if it is in fact the fuel pump. he looked something up and said @ least $750 (i now clearly remember why i stopped going to that shop ;-) slightly upset i left the Jeep there just for a positive identification of the error-code and if it is the fuel pump i'm following Eaglektd suggestion of replacing it myself. (unless the repair shop further away where my better half takes her car is dirt cheap for install)
post will be updated shortly... thanks!

|rudeboy||again, thanks man. and fyi the gauge still works + luckily i now know after a week that i need gas around 170mi|
|08-11-2011 09:27 PM|
|Eaglektd||Yea you're fine to keep driving it, you just won't know how much gas is in the tank so don't run out|
|08-11-2011 09:18 PM|
thanks Eaglektd, supposedly there's warrantee still on this Jeep.. i'll have to call the dealer (which is 2hrs away
JDsDream; i did Google the code, which i mentioned in my 3rd post ;-)
before i Google this, can i keep driving it w/o too much risk ?
|08-11-2011 09:08 PM|
I really hate it when someone tells me this but it really is helpful
In google search type in the code "p0463" and it will bring up articles addressing the problem and may even bring you back here right to the answer you need.

Well if it is in fact a faulty fuel sending unit and not some other weird electrical problem tripping it off, you would need to replace your fuel pump assembly as the sending unit is attached to the top of it. I can get under my Jeep without lifting it which would make it a little easier but it isn't the hardest thing to do if you're mechanically inclined.
To make it easier the less fuel in the tank the better to make it lighter, support the tank with a jack on a level surface and unbolt the metal straps holding the tank up to the frame of your jeep. Let the tank down slowly and give yourself some room to work and disconnect the electrical and fuel line connections from the top of the fuel pump assembly. I haven't done it on a JK yet but the fuel lines should be held on either by very tiny hose clamps or just the pressure of the rubber line going over plastic pieces on top of the pump. After the lines are disconnected turn the fuel pump counter clockwise like opening a jar, after you get it far enough it will stop turning and will just lift up and out.
Reverse the process to install it, once you get the new unit in it helps to have someone help you steady the gas tank as you raise it back up so it seats properly, you don't want to push it all the way up with the jack because you might dent or puncture the tank with the pressure (save that for a rock when your crawling).
This is what the unit looks like, hope this helps.

|rudeboy||thanks Eaglektd, i in the mean time found that it had to do with fuel, where do i go from here ? in case you know.|
|08-11-2011 07:56 PM|
That code is for your fuel sending unit
P0463 Fuel Level Sending Unit Volts Too High Fuel level sensor input above acceptable voltage.
P0463 (M) Fuel Level Sending Unit Volts Too High Circuit shorted to voltage between PCM and fuel gauge sending unit.

|rudeboy||ps. found out how to get a code and it's P0463. now for a list with the meanings of those codes|

fuel gauge and check engine light
just got home from our first topless ride (more on that later..) on the way back my better half drove. suddenly the fuel gauge went from full to empty (got gas this morning) and the check engine light came on. she stopped the Jeep, turned it off, waited for like 30 seconds, turned the key and the fuel gauge went back to full but check engine light is still on, so we drove it for another 5 minutes orso to get home. took off and put back the gas cap, which clicked but light is still on...
any guesses as to what is going on ? manual does not really help ;]
