Car Forum / Dodge / Dodge Cars / May 200695 caravan fuel gauge mystery
The fuel gauge is pegged at FULL and only begins to move when the tank is down to half or less. The DTE display seems to follow the fuel reading. Milage figures and other display numbers are OK. Is this a calibration problem or is there something going on with the sending unit? > The fuel gauge is pegged at FULL and only begins to move when the tank > is down to half or less.

Is the sending unit the traditional kind with a float and variable resistor? If this is so a reading near EMPTY would make sense if the float were sinking. Otherwise I suppose the float could be hung up or there is a problem with the resistor. Does the computer have a direct link to the gauge, or do they share the signal? Apologies for all the questions, i'm just trying to understand how it works. I'll try to find a shop manual and look for a diagram. > Thanks for comment.

The rheostat is bad causing the problem, in all honesty if you plan on keeping this vehicle you may want to replace the complete fuel pump assembly at one time if your going to go thru the trouble of removing it. the pump assembly is about $500.00 Glenn Beasley Chrysler Tech |
