Water Temperature Sensor
Water temperature sensor is tested by measuring resistance across sensor terminals. Resistance will vary with engine coolant temperature. See Water Temperature Sensor Resistances table.
WATER TEMPERATURE SENSOR RESISTANCES
| Coolant Temperature: °F (°C) | Resistance: Ohms |

| 14 (-10) | 7000-12,000 |
| 50 (10) | 3000-5000 |
| 68 (20) | 2000-3000 |
| 122 (50) | 700-1000 |
| 176 (80) | 200-400 |
