Temperature Gauge: Testing and Inspection

Temperature Gauge Pins - With Tachometer:

Temperature Gauge Pins - Without Tachometer:

1. Remove temperature gauge assembly from the cluster.
2. Check for continuity in wire between temperature sending unit and gauge (sensor input pin).
3. With ignition switch in On position, check for battery voltage across B+ pin and ground pin.

Multiple Gauge Malfunction

If the Temperature Gauge, Oil Pressure Gauge, and Speedometer appear to be malfunctioning, remove the cluster assembly and check the following:
1. Check for good 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.

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.
