Sensor, Coolant Temperature
The sensor is an NTC resistor (Negative Temperature Coefficient) which is powered with 5 V by the engine control module (ECM). Feedback is an analogue 5 V signal where the voltage level corresponds to a certain temperature. The resistance depends on the temperature according to the following:
| Temperature | Resistance |
| -20 °C | 15 kΩ |
| +/-0 °C | 5.7 kΩ |
| 90 °C | 240 Ω |
| 110 °C | 142 kΩ |
