Temperature Gauge: Testing and Inspection
Gauge Reads Low
1. Ensure terminals are clean and connections are tight.
2. Remove lead at sensor, measure resistance using an ohmmeter.
3. At 104 degrees F resistance should be approximately 1200-1350 ohms, and at 125 degrees F resistance should be approximately 53-55 ohms.
4. If resistance is not within specifications, replace sensor.
