Coolant Temperature Sensor
Connect ohmmeter leads to both terminals of sensor. Readings should be as specified for corresponding temperatures. See COOLANT TEMPERATURE SENSOR RESISTANCE table. If not, replace coolant temperature sensor.
COOLANT TEMPERATURE SENSOR RESISTANCE
| Temperature °F (°C) | Resistance (Ohms) |
|---|---|
| -4°F (-20°C) | 14,600-17,800 |
| 68 (20) | 2250-2650 |
| 176 (80) | 290-350 |
