Coolant Temperature Sensor
Using a DVOM, measure resistance between coolant temperature sensor terminals. For coolant temperature sensor location, see Fig 1. See COOLANT TEMPERATURE SENSOR RESISTANCE table. If coolant temperature sensor is not within specification, replace sensor.
COOLANT TEMPERATURE SENSOR RESISTANCE
| Temperature °F (°C) | Ohms |
|---|---|
| -4 (-20) | 10,000-20,000 |
| 32 (0) | 4000-7000 |
| 68 (20) | 2000-3000 |
| 104 (40) | 900-1300 |
| 140 (60) | 400-700 |
| 176 (80) | 200-400 |
