Charge Air Cooler Coolant Temperature Sensor
FUNCTIONS WITHIN THE SYSTEM
ECM receives the charge air cooler coolant temperature signal from the charge air cooler coolant temperature sensor and performs various control.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
The charge air cooler coolant temperature sensor is used to detect the charge air cooler coolant temperature.
INDIVIDUAL OPERATION
The charge air cooler coolant temperature sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
| Temperature [Deg. C (Deg. F)] | Voltage* (V) | Resistance (kOhm) |
|---|---|---|
| -10 (14) | 4. 4 | 7. 0 - 11. 4 |
| 20 (68) | 3. 5 | 2. 10 - 2. 90 |
| 50 (122) | 2. 2 | 0. 68 - 1. 00 |
| 90 (194) | 0. 9 | 0. 236 - 0. 260 |
*: These data are reference values and are measured between ECM terminals and sensor ground.
COMPONENT LOCATION
The charge air cooler coolant temperature sensor is mounted in the middle of the charge air cooler cooling electric water pump and sub radiator.
