Turn the ignition switch OFF.
Disconnect the ambient temperature sensor.
Check the resistance of the ambient temperature sensor between terminal “+” and “-” whether it is changed by changing of the ambient temperature.
Ambient temperature [℃(℉)] | Resistance [㏀] | Voltage [V] |
-30(-22) | 480.41 | 4.71 |
-20(-4) | 271.21 | 4.50 |
-10(14) | 158.18 | 4.20 |
0 (32) | 95.10 | 3.80 |
10 (50) | 58.80 | 3.31 |
20 (68) | 37.32 | 2.77 |
30(86) | 24.26 | 2.24 |
40(104) | 16.13 | 1.75 |
50(122) | 10.95 | 1.34 |
If the measured resistance is not within specification, substitute with a known-good ambient temperature sensor and check for proper operation.
If the problem is corrected, replace the ambient temperature sensor.
Disconnect the negative (-) battery terminal.
Remove the front bumper cover.
(Refer to Body - "Front Bumper Cover")
Disconnect the ambient temperature sensor connector (A).
Remove the ambient temperature sensor (B).
Install in the reverse order of removal.
