Fuel Level
The scan tool displays
5.00 to
0 Volts. The
PCM supplies a
5 volt signal circuit to the
fuel level sensor. The float inside the
fuel tank is connected to a variable resistor which causes the signal voltage to change with fuel level. The PCM converts the signal voltage to a fuel level value. The scan tool displays close to
0.8 volts for an empty tank, and close to
2.5 volts for a full tank.
