It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.Google+

The fuel gauge wont read correctly. Some times it is pegged and sometimes its somewhere in between. Today it worked correctly but the Voltmetter did not. It was pegged. Any ideas?

erratic fuel gage started acting up during record hot weather, maybe unrelated. mechanic recommended changing sensor and fuel pump even though mileage is low
fuel gauge/milage estimator not working. replaced level sending unit and pump just to be safe. good to go now
