Gas gauge is not reading correctly. Shows a full tank but the tank is not full. The gauge will not move from full tank until more than half a tank is gone. I have a 2002 Cadillac Deville DTS. How can I fix this?
The problem is caused by a defective gas gauge sending unit, this part is located inside the gas tank, you must remove the gas tank to replace it.
Weired i have the same problem with my 2002 deville. my gas guage dont work either same thing says full then dropps to empty when dry empty. emissionwiz had the answer but im wondering how much it costs to have the gas tank dropped and a new sending unit put in. any idea?
