ABSTRACT:
A fuel tank module control system configured to measure fuel level and fuel tank vapor pressure, the system having an aspirator to use air or liquid fuel to vapor, an oscillator cyclically producing pressurized vapor, and a pressure sensor that alternately measures the pressurized vapor provided by the oscillator and the pressure of a fuel column. A check valve is provided downstream of the sensor to restrict the flow of vapor in a single direction. To determine the fuel level, the differential of the square wave output of the sensor is calculated. To determine if there are any leaks in the fuel tank, the tank vapor pressure is measured when the engine is off.
