Question about Dodge Dakota

2 Answers

The gas gauge on my 2004 Dodge Dakota (4.7 V8) will suddenly drop from full (or wherever it actually is) to EMPTY and the Check Engine light will come on at the same time. After I shut the engine off and wait a few minutes AND CRANK IT BACK UP, the gauge will work correctly and the Check Engine light will have gone off. After I drive about 5 minutes, the same thing happens. The truck always runs normally when this happens. It did not happen for 3 days and it just started doing it again today. ANY IDEAS??

    I looked underneath my truck and the dash for a possible loose wiring connection but did not see anything - can anyone put me closer?

    Can you tell me where the fuel level sensor wiring is located??

    Can you tell me where the fuel level sensor wiring would be located? Thanks!

  • vsmcdowe May 19, 2011

    Thank you. I guess if that is the case, the gas tank has to come off?? Is it a part of the fuel pump and is it all one combined unit? That is what I have been afraid of...

    Thank you so much for the information. I had hoped that it would be something simple like a bad fuse or something but that is the way it goes sometimes. I bought this Dakota 4x4 Quad cab two months ago and since then I have replaced the complete front driveshaft due to a bad u-joint that is made into the driveshaft - $250. Now another $200 + ... 3rd Dakota I've had and I never had any major problems with them. Like the song goes....two out of three ain't bad....
    Thanks again!

    Hi,
    To follow up with you on my Dodge Dakota fuel level sensor issue...I took my truck to Advance Auto Parts today when the light came on again and the fault code that came on was PO 463, which is the fuel level sensor, as you did predict. Funny thing...when I filled my truck up with gas, the check engine light went off and my gas gauge is again working normally. Do the level sensors usually do this when they are going bad??
    Thanks again!

Hello
I suspect the problem you have is related to a defective fuel level sensor inside the fuel tank, but to confirm the check engine light and the gauge are related you will need the OBD2 electronic engine control system tested for fault codes, anytime the check engine light is turned on a fault code is set in the powertrain control modules memory. You can get the fault code test run for free at any Autozone, Kragen or Aamco Transmission shop. Let me know what the fault code is that shows up.

    It connects at the top of the fuel tank at the ring that retains the level sensor and the fuel pump module (fuel pump and level sensor are one part) into the fuel tank. There are no reported problems with the connector on this truck that I am aware of..

    All connections, especially grounding and fuel level sensor wiring should be inspected and cleaned.

Put in new float unit on fuel pump.gas gauge still not working


did you replaced just the float , because if the resistor that messures the level is not good you didn't do any thing you have to change the level sensor next to the pump..,Im sure that;s all the problem, you should also check the wiring next to the pumpand any connector down there
