Re: Reading for the DTE on overhead console is wrong
Check to make sure that you aren't changing between km/mph readings. I had the same problem when it was 90 degrees out side and the temp was registering in the thirties. It's the button on the left, should say something about KM/IMP or something...

could be the exterior temp sender unit these are usually mounted on the underside of the drivers door mirror or the display itself may be reading wrong get the OBD codes read as may tell which sensor is not reading correctly
The DTE is automatic and is the result of your previous miles per gallon multiplied by the gallons of gas registered in your tank.
Unlike the Trip miles, this DTE number can not be reset. It will vary by the fuel mileage per gallon recorded at each startup. That is why if you filled the tank and showed 400DTE you may have had 20 Gallons multiplied by 20 MPG. But if your new average is 16 MPG then it would show 320 DTE.
One tank of gas is not enough to compare mileage. Or are you saying the computer's readout of mpg estimate is showing less? Try a tank or two of premium and see if that helps. Keep track of gas mileage. Driving techniques have a lot to do with gas mileage, as does long trips vs. short trips, highway cruising vs. city driving. For best mileage, do regular maintenance and keep the car in top running condition-good spark plugs and clean filters and clean oil ! Attend to minor problems before they escalate. If you want to check actual miles per gallon, start with a full tank. Write the odometer reading down, and go. Everytime you put gas in, write down the amount. When you are close to 1,000 miles from the time you started, go fill the tank and include that amount of gas to your previous list. Now add up all the gas used and divide it into the miles to get miles per gallon. (976 miles/31.8 gallons = 30.69 mpg ) . Only one tank will skew your numbers, might be off cause the tank was filled more to the top than the previous fill-up. About a thousand miles of driving will give you a very accurate figure of miles per gallon for your car.
The float mechanism (or fuel level sender) on your fuel pump may be stuck or damaged. Attached is a digram of a typical fuel pump that is located inside the gas tank of your Dodge Durango.
You will need to remove your gas tank and pull out the old fuel pump to see if this is the problem. If you do this I would replace the fuel pump with a new one.
The overhead console is quite prone to internal failure. Dim,
intermittent, or dead displays are a common symptom of an internal
failure. We offer a
reasonable repair service with a lifetime guarantee. Check it out:
it mean that one of the electronic load leveling sensor is not reading. that sensor tells the air pump to fill up that air shock or air bag. the sensors maybe reasonable price wise but if the sensor is reading that an air shock is not holding air pressure and an air shock is not cheap.
