Q: Fuel gauge false readings

asked by on

The sending unit for the fuel gauge in the fuel tank sticks and gives false readings to the fuel gauge in the instrument panel.

Hi. I would recommend having a certified mechanic remove your fuel tank and inspect the sending unit for proper operation. There may be something in the way of the arm that is moving up and down with gas level causing inaccurate readings. Also, the rheostat may be faulty, sending the wrong voltages to the instrument panel.
