Fuel Gauge Sender: Testing and Inspection
Fuel Level Sensor Helpful Information
Gas current flows through coils in the fuel gauge, it creates a magnetic field. The magnetic field controls the position of the fuel gauge pointer.
The fuel-level sensor contains a variable resistor. As the position of the float arm on the fuel-level sensor changes, the resistor changes the current flow
through the fuel gauge circuit. A change in current flow alters the magnetic field in the fuel gauge, which changes the pointer position.
^
Circuit G4 connects to cavity 13 of the Powertrain Control Module (PCM) connector. The PCM determines low fuel level from circuit G4.
Refer to Group 14 for fuel system operation.
^
Circuit K22 delivers the TPS signal to the PCM. Circuit K22 connects to cavity 10 of the PCM, and cavity 2 of the TPS connector.
^
The PCM provides a ground for the throttle position sensor signal (circuit K22) through circuit K4. Circuit K4 connects to cavity 51 of the
PCM connector, and splices to cavity 3 of the sensor connector.
