Fuel Gauge Will Not Read Below 1/2 Tank

The fuel gauge may not go above or below 1/2 tank on some 2015-2016 Colorado and Canyon models.


If this condition is found, inspect the fuel level sender to ensure it is in the correct slot of the fuel module. If the fuel level sender is in the wrong slot, it may contact the side of the fuel tank (Fig. 15), resulting in an incorrect fuel level reading.
