Temperature Sensor (Gauge): Testing and Inspection

1. Turn ignition switch to On or ACC position.
2. Connect a 10 ohm resistor between gauge lead and ground. The centerline of pointer should fall within the band around the H mark.
3. Connect a 73 ohm resistor between gauge lead and ground. The centerline of pointer should fall within the band around the C mark.
4. If gauge tests within calibration, replace sender.
5. If gauge is out of calibration, replace gauge.
