Turn the ignition switch OFF.
Disconnect ambient temperature sensor.
Check the resistance of the ambient temperature sensor between terminals 1 and 2 whether it changes by changing the ambient temperature.
Ambient temperature [℃(℉)] | Resistance between terminals 1and 2 (㏀±3%) |
-30(-22) | 480.41 |
-20(-4) | 271.21 |
-10(14) | 158.18 |
0 (32) | 95.10 |
10 (50) | 58.80 |
20 (68) | 37.32 |
30(86) | 24.26 |
40(104) | 16.13 |
50(122) | 10.95 |
If the measured resistance is not within specification, substitute with a known-good ambient temperature sensor and check for proper operation.
Replace the ambient temperature sensor if it is proved that there is a problem with it.
Disconnect the negative (-) battery terminal.
Remove the engine room under cover front panel (A).
Disconnect the connector and then remove the ambient temperature sensor (A).
Install in the reverse order of removal.
