Inspection
1. | Ignition "OFF"
2. | Disconnect ambient temperature sensor.
3. | Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature.
1. Sensor Ground | 2. Ambient Sensor Signal
Specification
Ambient temperature [°C(°F)] | Resistance between terminals 1and 2 (kΩ)
-30(-22) | 479.22
-20(-4) | 271.45
-10(14) | 158.32
0 (32) | 95.10
10 (50) | 58.76
20 (68) | 37.30
30(86) | 24.27
40(104) | 16.17
50(122) | 11.00
4. | If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and check for proper operation.
5. | If the problem is corrected, replace the ambient temperature sensor.
Replacement
1. | Disconnect the negative (-) battery terminal.
2. | Disconnect the connector and then remove the ambient temperature sensor (A).
3. | Installation is the reverse order of removal.
