Circuit/System Description

The liquid propane gas control module monitors the signal of the of the primary fuel level sensor to determine the amount of liquid propane in the tank. The liquid propane gas control module uses this signal in order to calculate the percentage of remaining liquid propane gas in the tank and converts it to a PWM signal sent to the ECM. The ECM sends the fuel level percentage via the serial data to the instrument cluster in order to control the fuel gauge. The secondary fuel level sensor is only used as a input to the liquid propane gas control module to transfer fuel to the primary tank.
