Testing Fuel Gauge for Spirit L4-153 25L SOHC VIN K TBI (1993)
Fuel Gauge: Testing and Inspection
Fuel Gauge Test
Fuel Gauge Pins With Tachometer
Fuel Gauge Pins Without Tachometer
1.
Remove fuel gauge from the cluster.
2.
Check for continuity in wire between fuel tank sending unit and gauge (fuel level input pin).
3.
With ignition switch in On position, check for battery voltage across B+ pin and ground pin.
Multiple Gauge Malfunction
If the Fuel Gauge, Voltage Gauge, and Tachometer appear to be malfunctioning, remove the cluster and check the following:
1.
Check for good pin contact between the wire harness and the printed circuit board.
^
If there is good contact, check for ignition voltage at cavity C of the black connector.
2.
If there is ignition voltage, check for continuity between wire harness ground cavity H of the black connector and ground.
^
If there is continuity, replace the printed circuit board.
If the Temperature, Fuel, and Voltage gauges appear to be malfunctioning, remove the cluster assembly and check the following:
1.
Check for good pin contact between the wire harness and the printed circuit board.
^
If there is good contact, check for ignition voltage at cavity J of the red connector.
2.
If there is voltage, check for continuity at cavity H of the black connector.
^
If there is continuity, replace the printed circuit board.
