1. Remove lead at sensor, measure resistance using an ohmmeter.
2. At 104 degrees F resistance should be approximately 1200-1350 ohms, and at 125 degrees F resistance should be approximately 53-55 ohms.
3. If resistance is not within specifications, replace sensor.
4. Disconnect lead at sensor and gauge, check for a high resistance using an ohmmeter. Repair wiring if necessary.
