Dodge Caravan Fuel Gauge

Was the fuel sending unit replaced also?

the fuel level sensor is a float off the side of the fuel sender. over time these floats can become weak at the pivot point and read inaccurately. fuel sender should be replaced to correct this problem

This problem is due to a failure of the electronics that drive these gauge displays. What must be done is to have the instrument cluster removed from the car and sent out to a factory approved repair center for repair and upgrades. This is a common issue on the van

You have blown a fuse..check fuse box. There may be one fuse box one in the cabin but also check for the fusebox in the engine compartment.

The #1 most common cause of the fuel level gauge not working is the fuel level sending unit inside the fuel tank. The fuel tank must be dropped down and out of the Van to service the fuel level sensor.

Probably not. Sounds like a bad ground. The ground connecting point for the door is behind the drivers side kick panel, lower left. And the ground for the fuel sending unit is on the drivers side fender well. First I would unplug the connection at the tank (you can usually access this plug without drooping the tank) and check for corrosion. Clean it if any and take a paper clip and bend the tabs a little in the plug to make a better connection.

the level sending unit in the tank is attached to the fuel pump module it is a varible resistor it moves as fuel level changes this sending unit can be replaced but if your going to the trouble of replacing it you just as well replace the fuel pump it comes together.

Blown Fuse or fried Circuit board. Take to a local AutoZone, Advance, Murray's, O'reillys or a similar part house for them to check the wiring. I'm assuming the van does not use a mechanical Speedometer or Fuel Gauge.

On the plus side, with no speedometer, your indicated odometer mileage does not increase. Just keep your speed down and your tank full. Kidding, just kidding.

Filter is mounted directly above the pump module on top of the fuel tank. You may have to drop it down a little bit to change it. Also check the fuel pressure with a good gauge while it's running poorly and see if it's out of spec.

check the grounds on your fuel tank sending unit,must drop the tank to do this. with the tank down,remove the ground and look at your fuel gauge it should read full or empty,if it does not it may be a sending unit
